DENVER, PA.- 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 Morphy’s Automobilia, Petroliana & Soda Advertising auction held July 15-16.

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 sale’s overall gross of more than $1.6 million (including the buyer’s premium). The event was held live at Morphy’s flagship Pennsylvania gallery, with all forms of remote bidding available.



The circa-1940s Harbor Petroleum Products Co (Los Angeles) porcelain sign with seaplane graphics, 39 inches 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 Harley’s OHV V-twin legacy. The ’39 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 beautifully 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, circa-1930s Richlube Motor Oil double-sided porcelain sign. The sign, with original ring and base, was large at 63 inches by 27½ inches by 22 inches. It came into the sale with a modest $3,000-$6,000 estimate but ended up realizing $23,370.



A circa-1950s two-piece porcelain neon skin sign for Flying A Gasoline, showing a cookie-cutter-style edge as well as good color and gloss throughout the field, nearly doubled the $12,000 high estimate with a final selling price of $22,755. Both access panels were intact on the large and impressive 96-inch-diameter round sign, which was graded 7.0 for condition and ready for neon.



Also from Flying A, a 1930s aero-type double-sided porcelain sign, also round, was smaller than the above-mentioned example at just 36 inches in diameter. The sides were graded 8.0 and 7.0, respectively, with both sides showing good gloss and color throughout, although Side 1 had some light surface scratching and cloudiness spotting. The $14,760 sale price beat the $12,000 high estimate.

AGS liked what it saw in the rare, circa-1930s Super Shell Gasoline porcelain pump-plate sign, grading its condition at a near-perfect 95. Measuring 12¼ inches 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 the $20,000 high estimate to a final price of $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 inches tall by 90 inches wide, fetched $7,500. The 1950s sign was in pristine condition, graded 9.25+, and had the original wood backing. Ware Rogers Oil Company was headquartered in Springfield, Illinois.



All of the items described so far were sold on Day 1. The top lot on Day 2 was a circa-1910s Adam Scheidt Brewing double-sided sand-painted wood sign with the original iron hanging brackets. Graded 7.75 and 57 inches by 36¼ 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.

A large Squirt (“Never an After-Thirst”) single-sided tin billboard sign featuring the company logo and “Squirt Boy” mascot graphic, bested the $6,000 high estimate with a final selling price of $9,600. The circa-1961 sign was large at 120 inches by 48½ inches, and had a high grade of 8.9. The outer edges were concealed by the sign’s wood frame, which had been repainted silver at some point.



Standing 120 inches tall by 35¾ inches wide, an impressive Chew & Smoke (“Treat Yourself to The Best”) single-sided “Mail Pouch” tobacco porcelain sign, marked “Ingram Richardson” and graded 8.5, nearly doubled the $5,000 high estimate with a final price of $9,225. The sign’s field was nice and clean, showing only a couple of small chips to its outer area.
