These Climbing Monkey Toys were made in Germany by Lehmann from 1885 to 1945 and were designated EPL 385. The box art shows how it works. You put one end of the string under your foot and then pull on the top of the string and watch the monkey in felt coat climb to the top. This one has the metal pull tab in the shape of the Lehmann logo. This mint toy is shown with the original box in good condition. This is the plain version of the toy and box. Another version says “Tom” on the box and toy.
