#23: Buick Authorized Service Tin Sign (1950s) – $950
Nothing whispers mid-century elegance like the Buick logo in deep navy and crisp white. This service sign from the 1950s isn’t flashy, but it’s rich with dealership class. It once hung above hydraulic bays and chrome bumpers, quietly promising excellence to Sunday drivers and muscle car dads alike.

The tin litho surface holds its colors well, even if some rust ghosts around the edges. Buick isn’t the rarest in auto signage, but this model — round, legible, and era—anchored—carries enough prestige to stand proudly in a collector’s garage. It’s Midwestern luxury on a metal plate.
