A clean 1940s Harbor Petroleum Products porcelain sign with seaplane graphics glided to $54,120, a 1939 Harley-Davidson EL Knucklehead motorcycle roared off for $40,590, and a 1930s Ford double-sided porcelain neon sign with bullnose attachments brought $31,200 at Morphys Automobilia, Petroliana and Soda Advertising auction held July 15 and 16. The sale was loaded with nearly 1,300 lots of motoring-related signage and service station items designed to please even the most discerning collectors. Bidders responded with great enthusiasm, as reflected in the sales overall gross of more than $1.6 million (including the buyers premium). The event was held live at Morphys flagship Pennsylvania gallery, with all forms of remote bidding available. The ca. 1940s Harbor Petroleum Products Co (Los Angeles, Calif.) porcelain sign with seaplane graphics, 39 by 35 inches, was graded 9.0 by AGS, the premier authentication and grading service for antique advertising. It exhibited full color and gloss throughout, with great display power as an icon of early California petroleum history. The selling price of $54,120 was within its presale estimate range. The 1939 Harley-Davidson EL Knucklehead was a legendary motorcycle famous for establishing Harleys OHV V-twin legacy. That model year is prized by collectors, in part because the 61-cubic-inch (1000cc) engine could achieve speeds of 100 mph. This was an older restoration. The bike was mostly original, with chrome accents added later. The $40,590 final sale price was within estimate. The complete 1930s Ford double-sided porcelain neon sign with bullnose attachments was clean, with each side exhibiting outstanding color and gloss. The lettering was also in excellent condition on each side and lit up in bright neon. The 101-inch-wide sign was graded well at 8.75+ out of 10 for condition, and the $31,200 selling price topped the $30,000 high estimate. Bidders were willing to look past the heavy dirt and rust staining, field chipping and wear on an as-found, ca. 1930s Richlube Motor Oil double-sided porcelain sign. The sign, with original ring and base, was large at 63 by 27.5 by 22 inches. It came into the sale with a modest $3,000 to $6,000 estimate but ended up realizing $23,370. The AGS liked what it saw in the rare, ca. 1930s Super Shell Gasoline porcelain pump-plate sign, grading its condition at a near-perfect 95. Measuring 12.25 by 12 inches, the sign exhibited incredible color and gloss throughout, showing desirable heavy shelving between each color with an extremely clean field. Bidders agreed, pushing it to $22,200. An excellent example of a rare Ace High Motor Oil one-quart can, boasting great script and graphics, plus wonderful color and gloss throughout the field, breezed past the $6,000 high estimate to finish at $9,840. The can was empty, with both lids intact. It graded nicely at 8.75. A new/old stock single-sided tin Wareco Service Station figural billboard sign, featuring a graphic of Wareco Willie the service station attendant, massive at 96 by 90 inches, fetched $7,500. The 1950s sign was in pristine condition, graded 9.25-plus, and had the original wood backing. Ware Rogers Oil Company was headquartered in Springfield, Ill. All of the items described so far were sold on day one. The top lot on day two was a ca. 1910s Adam Scheidt Brewing double-sided sand-painted wood sign with the original iron hanging brackets. Graded 7.75 and 57 by 36.25 inches, the sign showed excellent condition glass graphics with reflective gold script on each side. The selling price of $12,000 was $2,000 above the high estimate.
