I've seen a few of these online but had never come across a pair out in the world until finding these the other day, and aside from a couple tiny losses to her left shoulder on the exterior, they are in great condition and I believe complete, right down to many internal organs! Each folds out in a series of layers, which I've tried to document fairly comprehensively--and which doing for the first time I might say is pure delight! I believe these were produced in the 1930 or 1940s, and I've seen one reference noting this set as having been included in The New People's Physician medical book.
Fully open" 16" x 12". Folded up with heads folded down" 8 7/8" x 5 3/4". Other than the tiny losses at her shoulder, these are in terrific complete condition.
