Over on the H.A.M.B.’s excellent pre-WWII photos thread, MrFire recently posted a couple links to the New York Public Library’s Flickr page, which contains some excellent automotive photography collections, including one of GMC trucks, divided roughly between the division’s early products and its art deco/streamline moderne trucks from the 1930s. We grabbed a selection of the latter shots, all showing GMCs at work. For somebody with some time on their hands, they could make up the foundation of an in-depth treatise on the services that trucks provide, and how those services evolve (or, in many of these cases, don’t evolve) over time. For the rest of us, we can still appreciate a shot of an old truck just for being a shot of an old truck, right?
