DENVER, Oct. 2, 2025 /PRNewswire/ -- Collectors will be "pedal to the metal" on October 4-5 when live bidding opens on 1,100 top-notch lots of automobilia and petroliana at Morphy's flagship gallery in Pennsylvania. The auction includes 813 outstanding advertising signs, 42 gas pumps, 57 gas globes, 55 product cans, and hundreds of other antique and vintage motoring-related items.

Many of the most coveted signs to be offered display mascots and graphics that are considered classics in the gas and oil advertising hobby. Two of the most recognizable were produced for Sinclair Oil Corporation, a company founded in 1916 with the combined assets of several small petroleum companies. Their distinctive branding, noteworthy for its logo featuring a green dinosaur named "Dino," became widely recognized, especially as the company expanded its operations and service stations across the USA.

The first Sinclair highlight is a coveted circa-1930s double-sided porcelain service station sign for Sinclair Aircraft Gasoline with the image of an early airplane. Both sides of this bright-red round sign display very good color and gloss, and very clean script, with only minor chipping. It measures 48 inches in diameter and is graded a strong 8.5 out of 10. Its estimate range is $25,000-$100,000.

Dino will amble into the spotlight in the form of a brilliantly-hued, double-sided Sinclair Pennsylvania Motor Oil porcelain sign. A striking graphic of the company's prehistoric mascot is accompanied by the phrase MELLOWED 100 MILLION YEARS. A great-looking example, it shows only minor chipping to side one. Side two has no notable field wear other than a few fine surface scratches. Sized 23¾ inches in diameter, this condition: 9.0 advertising gem is estimated at $10,000-$20,000.

Auction guests will be greeted by the bright colors of classic 20th-century automobilia signs as they enter Morphy's gallery. The top entry is a complete and outstanding "OK Used Cars Authorized Dealer" double-sided porcelain neon sign with a bullnose attachment mounted to the original can. Incredibly clean and in all-original condition, it boasts outstanding color and gloss throughout. The sign Illuminates beautifully in yellow, blue and red on each side, with a flashing "OK" button. This imposing condition 9.0 sign measures 60 inches by 44 inches by 21 inches and has a $20,000-$35,000 estimate.

Right alongside the "OK" dazzler, there's an outstanding Chevrolet Super Service single-sided porcelain neon sign in all-original condition. Free of any touchup or repair of any kind, it retains all of its original neon tubing, as well as its original metal hardware mounted on a newly-made metal can with new transformer and electricals. The sign illuminates in its original neon green and blue. Sized 56½ inches wide and 49 inches top to bottom, it is in 9.5+ condition and estimated at $15,000-$25,000.

Other highlights include a figural single-sided porcelain Mack Truck sign shaped like the 125-year-old company's beloved bulldog mascot, Mack, $5,000-$10,000; a rare and stunning 15-inch single globe lens that advertises Tiger Gasoline with a tiger graphic, $8,000-$12,000; a circa-1920s Wayne Model #452 double gas pump, $4,000-$8,000; and a 1935 double-sided "Drink Coca-Cola Fountain Service" porcelain "slasher" sign, $5,000-$10,000.
