Rare Collectibles at Morphy's July Automobilia Auction Set to Thrill Enthusiasts
Morphy Auctions, a renowned name in the collectibles market, is gearing up for an exciting event on July 15 and 16, 2026, as it hosts its Automobilia, Petroliana, and Soda Advertising auction. This eagerly awaited sale features nearly 1,300 lots, showcasing a diverse array of rare and desirable collectibles that are sure to entice motorsport enthusiasts and collectors alike.
One of the standout pieces in this auction is an incredibly preserved 1940s porcelain sign from Harbor Petroleum Products, complete with striking seaplane graphics. This piece measures 39 by 35 inches and has been graded 9.0 by AGS, a leading authentication and grading service for antique advertising. Its vivid colors and high gloss finish make it a must-have for collectors, with an estimated value between $40,000 and $80,000.
Motorcycle aficionados will be thrilled to see the inclusion of two iconic bikes: a 1939 Harley-Davidson EL Knucklehead and a 1947 Indian Chief Model 347B. The Harley-Davidson model, famous for launching the brand's OHV V-twin legacy, is estimated at $30,000 to $50,000. This motorcycle is particularly coveted, as the 1939 version marked a pivotal resolution to early oiling problems that had troubled its predecessors. The Indian Chief, known for its dominant presence on the road with distinctive skirted fenders, has undergone an older restoration and is valued between $15,000 and $30,000.
In addition to these motorcycles, the auction features several vintage signs that tell the story of America's automotive history. Among these is a double-sided porcelain neon sign for OK Used Cars, notable for its impressive 60 by 44 inch size and graded at 9.0+. This piece represents a significant era in American car sales and is estimated at $15,000 to $30,000.
