DENVER, Pa., Sept. 10, 2026 /PRNewswire/ — A 1906 Indian Camelback motorized bicycle built by The Hendee Manufacturing Company (later The Indian Motorcycle Company, with no “R” in motocycle), a circa 1930s Sinclair Aircraft double-sided porcelain sign with iconic airplane graphics, and a 1932 Cadillac 355-B seven-passenger Imperial limousine registered to notorious gangster Al Capone share top billing in Morphy’s October 4 Automobilia, Petroliana & Advertising auction.

The auction is packed with more than 650 lots of motoring-related signage, service station items and vehicles certain to please collectors at every price point. The event will be held live at Morphy’s Pennsylvania gallery, with all forms of remote bidding available, including live via the internet through Morphy Live. All items are available to preview at the gallery by appointment only from 9-4 ET.

Motorcycles like the 1906 Indian Camelback do not come around very often, and the one in Morphy’s auction is a true survivor in barn-fresh condition. The classic two-wheel bike retains its factory paint job in Springfield Blue, while the 311 cubic inch, 2.25-hp air-cooled single-cylinder motor with a production number of 2877 is untouched, with all major components intact. The motor turns over with good compression, the wheels spin freely, and the brakes work. Estimate: $80,000-$120,000

The round, circa-1930s Sinclair Aircraft double-sided porcelain sign, 47¾ inches in diameter, is a clean and glossy example of an iconic piece of advertising. It features the iconic airplane graphic on each side against a red background, and has only minimal chips and scratches. Graded in 9.0+ condition, the sign displays a rich gloss, with great shelving between the colors, and is one of the finest examples Morphy has ever offered. Estimate: $60,000-$90,000

The impressive 1932 Cadillac 355-B seven-passenger Imperial limousine with body by Fisher is finished in cream with burgundy fenders and accents. An extensive binder documents nearly $95,000 in mechanical restoration, refurbishment and detailing performed by Classic & Exotic Service in 2011 and 2012. A notarized New York Certificate of Sale identifies notorious Prohibition-era gangster Alphonse “Al” Capone as its original purchaser/owner. Rochelle Cadillac Co of New Rochelle, New York, is shown as the seller. Estimate: $50,000-$80,000

An extremely well-documented 1964 Chevrolet Impala finished in silver blue metallic over a coordinated blue bucket-seat interior has a VIN # of 41447S178226, identifying it as a genuine St Louis-built V-8 Super Sport hardtop. Power is supplied by Chevy’s top-rated dual-quad 409-cubic-inch  engine, producing 425 horsepower thru 11.0:1 compression. The odometer currently displays 52,659 miles. Estimate: $50,000-80,000

An incredible example of a single-sided porcelain neon sign for Chevrolet Super Service, in original condition free of any touch-up or repair of any kind, measures 48½ inches by 41½ inches by 8¾ inches and is graded 9.5+ for condition. The sign illuminates in original neon green and blue and has all of its original glass and hardware. Also, it is mounted on a newly- made custom metal can in flawless condition. Estimate: $20,000-$30,000
