This historic photo came from Apollo 13 onboard module. The print is 4” x 5” and you can see the contact negative on the print (reverse printed). It was acquired from a Grumman employee of many years. Most of these photos this size were used to categorize images to use for map making or archiving then destroyed—luckily this one survived. The back is stamped with the mission archive # and you can look it up and see it is in the historic archives. It also bears the initials LM (lunar module) in pencil below. The info pasted below is cortesey of NASA archives:

AS13-60-8703 (11-17 April 1970) --- This outstanding view of a near full moon was photographed from the Apollo 13 spacecraft during its trans-Earth journey homeward. Though the explosion of the oxygen tank in the Service Module (SM) forced the cancellation of the scheduled lunar landing, Apollo 13 made a pass around the moon prior to returning to Earth. Some of the conspicuous lunar features include the Sea of Crisis, the Sea of Fertility, the Sea of Tranquility, the Sea of Serenity, the Sea of Nectar, the Sea of Vapors, the Border Sea, Smyth's Sea, the crater Langrenus, and the crater Tsiolkovsky.
