This portfolio (set of 12 large cards) is very interesting and comes in a nice kit with manual to explain the procedure for using it. It is marked 1950 and the images are printed on very heavy card stock. The drawings are very bold with strong design possibilities. This set was made to determine certain traits one might have: Oedipal intensity, penis envy,anal sadism and many more. Very interesting to look at and they make a memorable wall display if framed.
