The auction was timed to coincide with the very popular Iowa Gas Show in Des Moines, Iowa.

(DES MOINES, Ia.) – A rare General Gasoline double-sided porcelain transitional sign – showing the iconic Mobil Pegasus logo, signaling Mobil’s acquisition of General Gasoline and establishing its presence in the Western United States – sold for $18,150 at an auction held Aug. 1-2 by Matthews Auctions, timed to coincide with the popular Iowa Gas Show in Des Moines.

The shield-shaped sign, rated 9+ out of 10 for condition and measuring 42 inches by 34 inches, advertised Socony-Vacuum Products and boasted great gloss and color. The fields were clean and the only flaws were a few small chips at the left-hand bottom point. In the end, its rarity and condition are what drove the price skyward. The sign was the top lot of the auction.

In all, about 650 lots of petroliana (gas station collectibles) and automobilia came up for bid over the course of the two days. “It was a good, strong auction, with spirited bidding both in person and online (through,” said Dan Matthews of Matthews Auctions. “We had a good selection of merchandise from the 50 or 60 consignors. The hobby is extremely healthy.”

More than 200 people attended the auction in person, and about that many registered to bid on the Internet. “There were lots of phone and absentee bids as well,” Matthews said. “It was just a great sale all around.” The second top lot was a Saxon Motor Oil double-sided porcelain sign, 18 inches by 18 inches, rated 8 and 7.5, with good gloss and color. It hammered for $9,350.

Following are additional highlights from the auction. All prices quoted include a 10 percent buyer’s premium.

A rare Oldsmobile Service Rocket double-sided porcelain die-cut sign – the first example of this rare sign ever offered by Matthews Auctions – rated 9 for condition and measuring 10 inches by 59 inches, went to a determined bidder for $8,800. Also, a Union Minute Man Service double-sided porcelain sign with the Speedy logo, rated 8.5, also quite rare, topped out at $7,150.

Many Mobil signs came up for bid, mainly because the auction included the second half of a big Mobil collection. A Mobiloil Aero single-sided porcelain shield-shaped sign, 13 inches by 12 inches and rated 9, with Pegasus logo, brought $6,600; and a very rare Mobil Kerosene single-sided porcelain shield-shaped sign, with Pegasus, made in 1955, rated 8.9, fetched $6,050.

(Minneapolis) rose to $4,400.

The other was a set of Mobiloil Arctic Special Fulpruf oil bottles with rack, rated 9+, in great condition, measuring 22 inches by 19 inches by 10 inches.
