“Sesquicentennial, Canton 1955”
Well, it wasn’t Canton Michigan’s Sesquicentennial (I checked, 1984) so it must have been Canton Ohio’s! Their’s was in 1955 which would date this photo remarkably well. But you don’t care about that, you just want to know what the emotionless man in the derby drives. It’s a 1951 Cadillac Coupe DeVille, it is.
