Based on the plastic model kit from 1968 by famed car designer Tom Daniel.
From the model description:
Talk about a cherry show rod! The Pie Wagon is the latest hit sensation! It's a groove, a gas and also custard and banana cream! Created by Tom Daniel, West Coast rod designer, it's a wild custom built delivery truck full of all kinds of new goodies. Loaded with chrome and BRASS plated parts, it's the standout in any collection of show car models. From its brass 'T' radiator to the opening rear door and cargo of pies, it's the most in mad, mod haulin' machines!
