Here we have a wonderfully American little time capsule: a trio of mid-century gasoline advertising thermometers, promoted for Gulf, Texaco, and Standard service stations. These were the sort of practical giveaways that once hung in garages and repair shops, quietly doing two jobs at once — telling the temperature and selling a brand.
The graphic design is pure roadside Americana: bold logos, red-white-blue palettes, and the cheerful confidence of postwar marketing. The molded plastic bodies and printed inserts are consistent with mid-20th-century production, likely 1950s into the 1960s. The base text naming individual service stations is especially charming and helps place them in that local-business culture of the era.
Condition is quite respectable for display. There’s visible age toning, dusting, and scattered scuffs, but nothing here looks alarmingly modern or over-restored. The thermometer tubes remain intact and the graphics retain strong color, which is exactly what collectors like to see.
Authenticity score: 78%. These look genuine, but the category does attract reproductions, so I’d stay conservative without a hands-on inspection.
Auction estimate: $75–$175 for the trio if authentic; $25–$75 if later reproductions. A neat little set — the sort of thing that makes a collector smile before the auction hammer even falls.

Curator Questions
Curated by Jade
Assessment:
A desirable trio of vintage gas-and-oil advertising thermometers, attractive as a matched display group. The printed logos, molded plastic construction, and period service-station text are consistent with mid-century promotional pieces. Visible wear, soiling, and light aging support age, though these are common enough collectibles rather than rare shop signs.

Provenance:
No formal provenance provided; names and addresses printed on bases only.
Condition:
Very Good (light wear, surface grime, minor age toning; not officially graded)
Identification Score: 96%
The logos and slogans clearly identify these as promotional service-station thermometers for Gulf, Texaco, and Standard. Form, graphics, and construction are strongly consistent with mid-century advertising pieces.
Authenticity Score: 78%
The pieces show convincing age-related wear, slight discoloration, and period-correct printing and construction. They appear genuine, though the market is full of later souvenir and reproduction versions, so I would keep the attribution conservative without closer examination of mounting details and backs.
