Sinclair Aircraft Large 30-Inch Vintage Service Station Porcelain Enamel Sign
Sinclair Aircraft – The Wings of American Innovation
Before commercial airlines ruled the skies, Sinclair Aircraft was fueling a generation of pilots, barnstormers, and daredevils with bold branding and premium fuel. This 32” porcelain enamel sign features the classic Sinclair Aircraft logo—with clean lines, aviation-inspired fonts, and that unmistakable flying dinosaur—capturing a moment when aviation was young, adventurous, and wide open.
Whether you’re building a vintage garage, outfitting a hangar, or simply honoring the golden age of flight, this sign delivers history with presence.
Remember when people were proud to own things? When American-made meant something?
We do too. That’s why we build these signs the right way. This Sinclair Aircraft 32” Porcelain Sign is made with real kiln-fired porcelain enamel, fused onto ¼-inch thick, heavy-gauge steel, giving it the lasting durability and rich finish collectors expect.
Built Like the Originals—Because It Is.
After 15 years as an auctioneer and a lifetime as a collector, I’ve seen how craftsmanship disappeared from the market. Most reproductions today are flimsy aluminum or sticker prints. This isn’t one of those. This sign weighs in at a hefty 18–22 lbs, with hand-punched mounting holes and a finish that feels like it flew in from 1937.
Key Features:
✔ 30” diameter – Large format, perfect for standout display
✔ ¼” heavy gauge steel – Substantial weight and long-lasting durability
✔ Kiln-fired porcelain enamel – Glossy, fade-resistant, and weatherproof
✔ Hand-punched mounting holes – Authentic to vintage manufacturing
✔ Weatherproof for indoor or outdoor display
✔ Approx. 18–22 lbs – Heavy and solid, just like originals
Satisfaction Guaranteed.
We stand behind every piece. If you're not thrilled, return it—no questions asked, and we’ll even pay the return shipping.
