Introducing the Texaco Gasoline Motor Oil Porcelain Sign — a striking embodiment of vintage American road culture. This eye-catching, round sign once served as a beacon to travelers, promising quality and service under the expansive banner of the Texaco brand. Sizeable and built from robust materials, it captures attention with the timeless red star and green 'T' logo, iconic to Texaco’s erstwhile roadside charm.
Dated to the 1930s and 1940s, this piece flourished in the golden age of service station signage. Texaco, or The Texas Company, as boldly inscribed beneath the star, commissioned these durable signs to affirm their widespread presence and enduring reliability to customers across the United States. Today, this sign not only represents a bygone era but stands at the crossroads of Americana and collectible petroliana.
Made from porcelain enamel on steel, this sign is a testament to the craftsmanship of its time. Porcelain enamel was favored for its lasting vibrancy and ability to withstand the elements, making such artifacts highly coveted by collectors. The mounting grommets, a signature of its original use, further authenticate its place in historical advertising.
The ravages of time and weather have left their mark, with extensive rust and chipping adding layers of character to this collectible. While it shows considerable wear with some lettering obscured, these very flaws can attest to its authenticity. The textual design remains largely intact, providing that nostalgic visual punch collectors find irresistible.
Assessed with an authenticity score of 85%, the sign’s weathered features lean strongly toward genuine age. It holds a value estimate of $600 to $1,200 at auction given its condition, a worthy sum for those passionate about vintage advertising. While newer reproductions are common, the patina of age sets this sign apart, echoing its storied past. Thank you for turning back the pages of history with this relic of the highway's golden days.

Curator Questions
Curated by Jade
Assessment:
This is a highly collectible piece of American petroliana, representing the golden age of roadside and service station advertising. The extensive rust and chipping are typical for signs left exposed to the elements, yet the bold Texaco graphics remain highly desirable to collectors. While condition issues affect top value, genuine porcelain Texaco signs from this era are consistently sought after at auction.
Individual Images:
Key details: The close-up shows extensive surface rust and chipping typical of prolonged outdoor exposure. The mounting holes are heavily rusted
and there is loss of enamel
especially near the top-center and right edge
as well as on the 'CO' of 'TEXACO.' These factors support authenticity and indicate the sign was genuinely used in an outdoor installation.
Provenance:
No provenance documentation visible. Assumed found or collected from a service station environment.
Condition:
Fair (significant rust and porcelain loss, mounting holes worn, some lettering obscured)
Identification Score: 98%
The design, materials, manufacturing technique and visible wear are all consistent with authentic Texaco porcelain signs from the 1930s-40s. The specific logo and text layout match known period examples, making identification highly confident.
Authenticity Score: 85%
The heavy porcelain enamel, realistic wear, proper layout, and mounting grommets are all in line with authentic signage of this period. While high-quality modern reproductions exist, the degree and character of rust, edge wear, and color loss suggest genuine age. However, porcelain sign reproductions are common, so a physical inspection (checking back for stenciled numbers or evidence of newer materials) would be needed for 100% certainty.
Image Memory Note
The sign is a large, round, enameled steel service station sign for Texaco. Text around the red border reads 'GASOLINE MOTOR OIL.' Center features a large red star with a green 'T,' overlayed by the word 'TEXACO,' with 'CO' offset and 'REG. T.M.' in small letters beneath. Below the star: 'MADE BY THE TEXAS COMPANY.' Surface displays extensive brown rust patches, areas of chipping especially above 'TEXACO' and around some edges, and several heavily rusted mounting holes. White background has yellowed somewhat from age; no visible back side or stenciled markings. All text is easily legible despite damage.
