I'm not entirely sure whether this toy was created as I found it, or a one off creation of creative maker who combined treen canister, spring, and little man; I think likely the former--a genie in a box--but am not completely sure as I can't find another example out there like it. At any rate, the lid is threaded, and when you screw it off, up and out he springs! I believe most likely German Erzgebirge, and definitely with a good amount of age. One could also change him out with other figures for added excitement!
Treen canister measures 3" t x 1 3/8" d. All in very good condition, and quite a surprise when opened!
