Two different sets c. 1960s by Mectoy. Each colorful box contains hard plastic "track" base and hard plastic windup car driven by a different character. First set is "50 Circo Donald." Box is 6.75x13.75x1.75" deep. The circus-themed base includes Donald as animal trainer, Goofy juggling, Uncle Scrooge balancing on a ball as Pluto watches him, Donald's nephews in a circus wagon. The windup car is 1.25x2.5x2.5" tall and features one of Donald's nephews. Underside of car is missing one of two tiny pegs although this does not affect operation and car travels in a circle on the base. Second set comes in 8.5x11.75x1.75" deep box and is "60 Donald Conductor." Base illustrations are of Goofy riding a bicycle, Daisy watching an angry Donald getting tossed from a donkey, Donald's nephews watching Uncle Scrooge drive his car over tacks placed on the road by them. Car features Goofy as the driver. One of the two tiny pegs on underside has been reglued. Toy works and Goofy travels around the rather erratic path. Boxes have scattered trace of edge wear and some overall lt. pinpoint age spotting but Fine w/Exc. contents. Nice pair.
