You see a lot of these around, most people think there from the 70s/80s. But this model was produced from 1952 - 1961. They came with two different tires on them, the early ones (Orange here) has a smooth Rubber Tire, the later ones (Green here) came with patterned plastic tires. In 1957 General Mills ran a mail in promotion for the Cheerios City, there were four different sets, one included this jeep. You would get 4 cars and a layout instructions, the "buildings" were on the back of the boxes.
