This is a antique Louis Marx tin litho wind up called Ring A Ling Circus. If is being sold as is cause it’s missing the Lion and the Ring Leader. As far as the wind up function if actually does work but the monkey sometimes jams it up so if it stops you’ll need to pull the monkey up so it could continue so that needs to be addressed pretty cool piece nice side litho art if you have any questions or concerns please please ask before buying because there are no returns thank you for viewing.
