From the 1980's cultural tour-de-force movie "Dumb and Dumber", the 1984 Sheep Dog van is a perfect melange of functional utility, mobile advertising, and comfort. The van was distinctive, known by many young women as the "Shaggin Wagon" around Rhode Island, and is currently somewhere in America's Heartland. The next time you'll see it will be at Sotheby's auction house, fully restored to its past glory.
