Nice large cyanotype that depicts ancient goddesses in sequence. The statues sequence categorize discoveries through time. Clean and minimal yet large enough to be a centerpiece. Measures: 22" x 30"

Cyanotype is a photographic process where a light sensitive emulsion is put on the paper. A negative is placed on top of the sensitized paper and exposed in the sun. All of these prints are sun exposed and then developed in water and oxidizer causing the unique prussian blue on the paper. 

Each piece is unique and hand made from start to finish.

Very intricate leaf 'anatomy' patters that look like cells or a city from high above weaving in and overlapping. This piece was hand made using the cyanotype process. The process is an early photographic method that involves coating the paper with a uv sensitive liquid and using the sun to expose the image on the paper. The light rays turn the paper a permanent deep blue. The piece is printed on heavy Arches French watercolor paper measuring: 22.5" x 30"

Each piece is unique and is signed in pencil on the back. The last photo show another composition that is listed on the site.

Large skeletal cyanotype in a minimal classic anatomical pose. The piece is made using an actual drawing on film using ink and pen so you see the brush marks and hand rendering against the rich deep blue.  This piece is printed using the cyanotype photographic process where during development of the paper turns a permanent deep indigo blue. Printed on heavy drawing paper this piece measures: 31" x 77". Signed in pencil in the back of the piece by the artist

A technological artifact with great history. Historical information provided by Siemens and Doris-Maria Vittinghoff :

In fall 1958, at the age of only 43, Arne Larsson in Sweden appeared to be nearing the end of his life. He was suffering from cardiac arrhythmia which had worsened as a result of a viral infection. His heart was beating at a rate of only 28 beats a minute – a healthy heart beats approximately 70 times a minute. Larsson was constantly losing consciousness and had to be revived 20 to 30 times a day. There was scarcely any hope of a cure. But his wife Else-Marie refused to accept her husband’s impending fate. She read in the paper that the cardiologist Professor Ǻke Senning in the Karolinska Hospital in Stockholm was working with the doctor and engineer Dr. Rune Elmqvist on an implantable pacemaker. Ms. Larsson was convinced that this was her husband’s salvation – although up to then the developers had only experimented with animals and there was no device suitable for the human body.

Thanks to his wife’s powers of persuasion, Arne Larsson received his first pacemaker in a secret emergency operation on October 8, 1958.  Dr. Rune Elmqvist, the developer of what was the first pacemaker in the world, was an engineer at Elema-Schönander (later Siemens-Elema) and had previously worked as a cardiologist. For lack of time, he coated the components of the first device with epoxy resin in a simple plastic cup. Two electrodes connected to the pacemaker provided the energy to stimulate the heart. This first model had to be replaced by a new one after only a few hours. The technology however rapidly improved and models of increasing complexity met the specific requirements of a malfunctioning heart. Today pacemakers with a life of ten years are standard in modern cardiology.

Arne Larsson lived to be 86, surviving even the man who saved his life, and used a total of 26 pacemakers. Thanks to these small devices he was soon able to live an active life which once again included cycling, sailing, dancing and air trips.  At a congress in Vienna in 1983, Dr. Rune Elmqvist commented on pacemaker technology as follows: “I must admit that at first I viewed the pacemaker more or less as a technical curiosity. So it was fantastic to see its tremendous development.” In 1994 Siemens sold its entire pacemaker business to the American company St. Jude Medical.

During the Soviet invasion of Afghanistan in the 70's these pictorial rugs have become a tradition of telling a story. It is a historical marker of events, horrors, and yearning for peace. The rugs at first glance can seem unsettling but what they really are is a record of a point in time in a land of constant war. Some of these are made by weavers living in the north and are sometimes sold near military bases. The history of woven rugs contain symbols and characters that are ancient in tradition and passed down to future weavers. These rugs are contemporary versions, of that tradition, that carry symbols of recent events serving as a grim reminder, and also a constant bid for peace (note the dove carrying the olive branch) .  We have three different types in stock. Each is hand woven and made out of wool.  This piece measures 23.5" x 30"

The Operay Multibeam was first invented in the late 1930's as the first shadowless surgical light. It was quite sought after in operation amphitheaters that I have seen many ledgers where this lamp was the department highest equipment purchase for the year. This lamp had a short life span since its powerful arc would react to gasses in the operating room and cause explosions. Its successor was encased in a heavy cast iron housing and not as attractive. 

The mechanism consists of a bulb on the inside that reflects off six tiny concave mirrors that act as the focus to direct the beam through the prismatic lenses bouncing off the mirror plates and creating a singular focus. Typically this lamp had a large counter balance and is anchored to a high ceiling. This piece is just the main housing as it was found in a retired surgeons home in Wisconsin. He had kept the light as a memento from the Mendota Sanitarium that had seen the likes of patients such as Ed Gien among others.

The last few photos show how I have installed it in our show room with the use of scientific clamps to a T-bar as a solution for hanging. You can also add an additional light if you want on the top (socket needed) and hang it in a variety of ways. Meaures 12"to top of lamp (not flush mount) 33" at longest span 

Thick deep red ruby glass with aluminum mounting bracket. Piece is ready to go over a boring simple porcelain socket and spruce up your exit sign. Nicely aged font. Measures: 8" x 8" x 8" H 

Excellent cage lamp dating from the early teens with a retractable bottom opening for easy bulb change. Has original color on wood handle and extra long braided cord. Can be tied up and hung in many possible configurations. Measures 12" L and has a cord over 7' long.
