So many great variations on the classic rainbow colored stacking toy, and this is both an early one and a cool one, with one longer and narrower block meant to represent the trunk of a tree, on top of which the rest of the rounds stack. It of course does not need to be configured this way, and the "trunk" in combination with the other disks makes for arrangements that I think are especially sculptural and 1940s modern looking!

7 1/2" tall x 3 5/8" in diameter. Well loved, with wear all over but structurally in great shape and still terrific looking to my eye. The threaded post screws tightly into the light green base (with remnants of a Holgate sticker still on it) and and blue top block.
