C. 1920s Milton Bradley Geometric Solids in Original Green Painted BoxI'm forever on the hunt for old boxes of geometric solids, used for teaching drawing, but they're hard to come by, and have become very precious. This set was produced by Milton Bradley (the green painted box has lost its label, but I know that's what they are) c. 1920s, I believe. Not complete mostly it is the "surfaces" that are missing (flat cardboard cutouts), but a few solids missing too, and I believe a couple of small square blocks were thrown
