Here we have a handsome trio of mid-century advertising thermometers — Gulf, Texaco, and Standard — the kind of cheerful roadside ephemera that once lived in garages, service stations, and repair shops. They are small, functional, and wonderfully branded: part temperature gauge, part miniature billboard.
Stylistically, these are classic American petroleum advertising pieces from roughly the 1950s to 1960s, when corporate identity was designed to be seen from the curb. The molded plastic bodies, bright printed logos, and glass thermometer inserts all fit the period well.
The construction is straightforward but telling: molded white plastic, applied or printed graphics, and brass-toned thermometer plaques. These were meant for everyday use, not luxury display, so originality and surface wear matter. Here, the aging looks believable — some scuffs, discoloration, and wear to the plastic and graphics, but nothing that screams modern novelty.
Condition is generally good, with visible use wear and a bit of grime, but no obvious catastrophic damage in the photos. That said, these are not rare museum pieces; value in this category tends to live in the charm, the brand names, and whether the set remains intact.
Authenticity score: 72%. Auction estimate: about $75 to $175 for the group if vintage; if later reproductions, more like $25 to $60. In short: cheerful little relics of the gasoline age — the kind of thing that can make a shelf feel like a two-lane highway.

Curator Questions
Curated by Jade
Assessment:
Decorative vintage gas-station promotional thermometers, likely genuine mid-century advertising pieces rather than modern fakes. The molded plastic construction, period logos, and service-station text fit the era, though condition and exact maker are unclear. Collectible interest is strongest as a grouped set.

Condition:
Good (visible scuffs, light discoloration, not officially graded)
Identification Score: 92%
The logos, slogans, typography, and molded plastic form strongly match mid-century petroleum advertising thermometers. I am very confident about the object type, though the exact manufacturer is not identifiable from the photos.
Authenticity Score: 72%
They show appropriate period graphics, age-consistent yellowing, and used surfaces, but the photos do not prove original manufacture versus later issue or replacement parts. Overall they read as vintage rather than modern fantasy pieces.
