The Shell service station in Winston-Salem, North Carolina, was one of eight shell-shaped buildings constructed by Quality Oil Company to promote the Shell brand.

Built in 1930, it's the last of the clam-like structures remaining. Located at Sprague and Peachtree Streets, it was restored in the late 1970s by Preservation North Carolina at a cost of around $50,000, which would be around $247,000 today. It's now a small museum and preserved as a historic landmark.
