A truck stop in Oklahoma has taken the vertical-car themes of Cadillac and Bug Ranches to new heights, standing an entire 18-wheeler on its nose, trailer and all. This big rig serves as a 50-foot-tall sign for Wilkin's Oklahoma Truck Supply, along Interstate 35 south of Tonkawa, OK. The truck's upright trailer is painted to read "Got Problems?" and "We Fix Trucks".
These trucks are a great example of how to push traditional advertising and make it something fresh and eye-catching. I think this might be concept work rather than actual ads, but the idea could be a great way to utilize semis, buses, and more.
