UPDATE: **SOLD** Was on Etsy for $40.

” have for sale an old windup toy called the Jumpin Jeep by Marx.. It is tin and from the late 1940’s after the war. It has been well played with and does have quite a bit of rust. The jeep, the front tires and one large tire isn’t that bad and the lithograph design is in good condition with minor rust. There is one large tire that needs to be replaced or repainted. The toy looks as though it was left outside laying on its side with one back tire perhaps in the dirt for some time. The bottom of the toy also shows signs of rust. The key is still present but it has been overwound. It moves a little but I can’t wind it. Overall I would rate it good simply because the lithos are still in pretty decent shape. The size of the toy is 5 1/2″ long about 4 1/2″ tall and 4″ wide from back tire to back tire”

Here’s pictures of a couple other jumping jeeps that realized $210 at auction in 2008.
