Early Texaco Gasoline Motor Oil Porcelain Service Station Sign
LANGUAGE UNLOCK
Glossary Roundup
Original Presentation Script
Let’s talk about this big, weather-beaten beauty: an Early Texaco Gasoline Motor Oil Porcelain Service Station Sign, straight out of the golden age of the roadside.
The round format, red star with green “T,” and the phrase “MADE BY THE TEXAS COMPANY” take us back to roughly the 1920s–1930s, when corporate branding was still finding its bold, iconic voice along America’s highways. For petroliana collectors, early Texaco pieces like this are core currency — they’re the visual soundtrack of interwar motoring.
What we’re looking at is porcelain enamel fired onto heavy steel, not just painted tin. Those deep rust blooms where the porcelain has chipped away, and the cratered mounting holes, tell the story of decades on a pole or building front. The wear is rough, but the kind of rough that’s hard to fake convincingly.
Condition-wise, this sign has been through some things: edge losses, impact scars, porcelain flaking. Yet the central star and lettering still command attention, which is exactly what drives value in this category. In petroliana, honest battle scars often charm more than a too-perfect surface.
On authenticity, I’d put this around 70 out of 100 — strong indicators of age and period graphics, with a small reservation because the Texaco market is swarming with reproductions. At auction, assuming it’s period porcelain, I’d expect in the range of $1,500 to $3,000; if it turned out to be a modern repro, more like $150 to $350.

Curator Questions
Curated by Jade
Assessment:
Classic early Texaco porcelain service station sign with strong period graphics and honest outdoor wear. Lettering style, the phrase “MADE BY THE TEXAS COMPANY,” and traditional porcelain fabrication with rusted steel showing at chips all support an early to mid-20th-century manufacture rather than a modern fantasy piece. Condition is rough but collectible: significant porcelain loss at the edges, rust blooms, and impact dents, yet the core logo remains bold and legible. In petroliana, authenticity and graphic power outweigh perfection; many collectors prefer this ‘found at the station’ look. A word about fakes.. petroliana, especially Texaco, is heavily reproduced, with lightweight steel, glossy modern finishes, and incorrect fonts; this example’s heavy construction and aged porcelain wear pattern read as consistent with a period original.

Condition:
Fair to good (heavy porcelain chipping, rust, edge damage, but graphics still strong and readable)
Identification Score: 95%
Distinct Texaco star-and-T logo, matching known early gasoline/motor oil service station sign designs, correct wording and layout for pre–World War II branding, plus appropriate scale and construction.
Authenticity Score: 70%
Porcelain thickness, rust patterns, and chipping look naturally aged; typography and logo proportions align with documented originals. However, the reproduction market for Texaco signs is intense, and without reverse-side and edge-by-edge inspection, some uncertainty must remain.
