Very fine condition. Only evidence of play are wear to the ball, and a single not in the pull-string.
I'm calling this a type II, where type I (1941) had four differently sized cups, and type III (1950) had train and other designs printed on it. All catalog photos of type I-III had steel axles.
Un-reinforced cardboard box, with damage to one end. Detached flap marked "COOPER | PAPER | BOX CORP | BUFFALO", with the "C" surrounding the rest, with "OOPER" as the bottom leg.
Box has "STUDIED AND COMMENDED PARENTS' MAGAZINE CONSUMER SERVICE BUREAU" logo on top left.
