This Jumpin jeep has some damage (as noted by the Facebook seller), but is still a fairly rare item. Thanks to Andy for sharing it.

“This vintage wind-up toy is perfect for collectors who appreciate the craftsmanship of the past. Made by Marx, this tin litho Smokey Sam Fire Chief Jeep Whoopie Car is a must-have for any vintage toy enthusiast. The brand, Marx, is known for producing high-quality toys that stand the test of time. This particular toy is vintage and has been used, but it still retains a lot of its original charm. It features a wind-up mechanism that spins the fire chief’s head. This toy has certainly been loved, and there’s some minor damage to the fire hat, front of the Jeep, and ladder on one side (see photos).”
