A psychedelically painted microbus was the grand prize in a national sweepstakes to promote the use of a company's credit card. Marketing bosses thought the Volkswagen microbus would liven up the routine of credit-card transactions. The 1959 VW prize is a swirling design of bright colors -- purple, red, green, yellow -- with a raspberry fox on one side. The VW logo on the front of the bus has been replaced with a peace sign. We like to think the prize looked just like this college van.
