Collectible Vintage Signs from Past Decades, Ranked

An absolute gem of a relic, the Smith-O-Lene Aviation Gasoline sign screams Art Deco gas culture with jet-age dreams — before jets were even a thing. With its sharp color blocking and airstrip-ready branding, this porcelain piece is a favorite among petroleum collectors.

Produced during the 1930s, it’s tougher to find in good condition, making clean specimens climb toward the $1,200 mark. The bold orange and navy combo pops like a neon sky, and minor chipping only proves its vintage wingspan.
