LAST CALL - FINAL TWO SALES. This is one of the last two auctions for these signs. After this sale and the next, they are gone for good. This is your last chance to bid and buy. We ship nationwide and handle everything from beginning to end. SINCLAIR AIRCRAFT - WHEN AVIATION WAS THE FUTURE There was a time when the sky wasn't the limit - it was the dream. And powering those early flights was Sinclair Aircraft Oil, proudly stamped with the brand that Americans trusted on land, sea, and now in the air. This sign captures that spirit of innovation, featuring bold red lettering and vintage styling that harks back to airfields, open cockpits, and the golden age of aviation. Whether you're into aviation history, Sinclair collectibles, or vintage Americana, this piece belongs on your wall right next to the propeller and the oil can. BUILT LIKE THE ORIGINALS - BECAUSE IT IS Real kiln-fired porcelain enamel on heavy-gauge steel, with hand-punched mounting holes and the weight, gloss, and depth of color that only true porcelain has. These are handcrafted authentic reproductions made with traditional techniques, the highest-quality materials, and an attention to detail that is second to none. Set one beside a vintage original and you cannot tell the difference. We are proud of that. SIZE & DETAILS - Size: 12-Inch diameter, exactly as shown - Construction: kiln-fired porcelain enamel on heavy-gauge steel, single-sided - Mounting: hand-punched mounting holes, just like the originals - Approx. shipping weight: 2 to 3 lb - Display: weatherproof porcelain for indoor or outdoor use - Condition: new, handcrafted authentic reproduction (not a vintage original) Size: 12-Inch, exactly as shown. This sign is NOT made to order and is only available in the size shown. SHIPPING & PICKUP We ship nationwide and handle everything from beginning to end. Every sign is professionally packed and shipping is billed separately at cost. Local pickup is available by appointment in Ocoee, Florida. FINAL TWO SALES. WHEN THESE ARE GONE, THEY ARE GONE - BID NOW.
