A half-century after building its first truck, Chevrolet took the design in another direction—with wider, larger frames that were coined the "square body." This third-generation of trucks lasted from 1973 until 1987, and restoring box body Chevys has become a popular hobby for many. These "It's Hip to be Square" T-shirts are the perfect complement to a box-style Bowtie truck owner or enthusiast. They feature five iconic trucks on the back of a beautiful metro blue cotton tee.
