#18: Firestone Tin Sign (1950s) – $2,800
Industrial yet sophisticated, the Firestone sign of the 1950s combined sharp branding with the no-frills promise of durability. Featuring bold red script and lightning bolt motifs, this tin piece hung proudly in service shops where greasy overalls were the dress code.

While Firestone signs are more common in tire form, signage like this is far less ubiquitous, nudging its value upward. A well-preserved finish, crisp lettering, and those great vintage mounting holes all tell the story of a sign that truly earned its keep.
