6" long tin litho and painted tin toy with built-in key. 1920s, Germany. Cart has numerous marks including Lehmann trademark "Made In Germany" plus patent dates on the back USA 1903 and 1907 and 1913. Toy works and when wound cart travels about. Painted tin driver and donkey show virtually no wear except for two tiny paint flakes on driver. Cart has some spots of oxidation on one side rail of cart and one-third of one of the two wheels. Wheels have different designs, both incorporating troll-like figures and the "Lehmann" trademark. One wheel is eccentric which causes the car to bob up and down as it moves forward. Fine.
