If I were forced to choose a favorite from the hundreds of pull toys Fisher Price has made over the years, this would be it: the Nifty Station Wagon from 1960, a miniature version of America's beloved family road trip vehicle.
This 13 inch long kitsch classic sports a removeable roof, lovely fake wood side panels, stylish white wall tires, moving headlight "eyes", and a little wooden family (mom, dad, child of indeterminate gender, and dog) who were precursors to the classic Little People.
A simple mechanism causes the kid and dog in the back seat to spin wildly to the accompaniment of a raucous noise as the car moves, just like in real life. Those Fisher Price toy engineers were geniuses.

Several people commented that they had never seen this vintage Fisher Price toy before, so I thought you might enjoy seeing the original advertisement, from the April 1960 issue of Playthings magazine (a trade journal). I have a small collection of vintage toy ads, catalogs, and brochures, and this is one of its highlights. Click on the pic to see it bigger and read the text.
