Overview
The item is a large vertical single-sided porcelain (SSP) sign for 'The General Tire', featuring their classic shield logo and drop-shadow typography. These long, narrow signs were typically mounted on service station pillars or door frames.
Story
The General Tire and Rubber Company was founded in 1915 in Akron, Ohio, and became a major player in the mid-century American automotive landscape. These heavy porcelain enamel signs were produced primarily between the 1930s and 1950s for authorized dealers and service stations. They were often manufactured by specialized industrial sign companies (such as Veribrite or Ingram-Richardson), though specific attribution requires a visible maker's mark on the lower edge.

Condition & Value
Based on the provided narrative, the sign shows authentic-looking edge chipping consistent with age and outdoor service station use. In petroliana, the condition of the 'field' (the main graphic area and logo) is paramount; edge wear is expected and tolerated, but chips or deep scratches in the central typography will impact value.
Full Research
Sold comps, value drivers, and venue guidance pulled from recent auction results.
The market for vintage petroliana and automobilia remains incredibly strong, particularly for authentic porcelain signs from major mid-century American brands. Vertical pillar signs are highly sought after by collectors because their narrow footprint displays exceptionally well in garages and private collections without consuming massive wall space. Prices are heavily venue-dependent, with specialized auction houses consistently achieving higher premiums than general estate sales.
▲ Heavy single-sided porcelain (SSP) enamel construction is the gold standard for petroliana collectors
▲ Classic 'The General Tire' shield logo and drop-shadow typography carry strong brand appeal
▲ Vertical pillar format is display-friendly and highly sought after for private garage collections
▼ Unverified dimensions — a smaller variant (e.g., 60-inch) typically commands less than the massive 78-inch versions
▼ Unverified field condition — any major chips or 'spiderweb' crazing in the central logo area would discount the value
▼ Unverified reverse side — heavy rust or structural weakness on the back could deter high-end collectors
Best Venue
List with a specialized automobilia/petroliana auction house (e.g., Morphy Auctions, Mecum, or Richmond Auctions) to reach the dedicated collector base. Prior to listing, carefully clean the surface with mild soap and water to maximize gloss, and measure the exact height and width to confirm the specific variant for the catalog.
Upside Potential
If the sign is confirmed to be the larger 78-inch variant and the central field is exceptionally clean (grading 8.5+ out of 10 with high gloss), it could reach or exceed the $1,700+ high end seen at premium auction houses.
Authenticity Risk
mediumVintage porcelain advertising signs are frequently reproduced due to high collector demand. While the reported edge chipping is consistent with authentic age, modern reproductions often artificially distress edges. Without seeing the back (to check for authentic layered enamel and heavy steel) or a maker's mark, a medium risk is warranted. Authentication of the porcelain layering and grommets is recommended before a high-value sale.
