When it comes to classic gas station advertising, few brands are as instantly recognizable—or as collectible—as Sinclair. With its iconic green dinosaur and clean, bold lettering, Sinclair captured the spirit of American travel and roadside service stations. But it wasn’t just about fuel—it was about branding that stuck.
Today, Sinclair porcelain signs are among the most sought-after pieces in the world of vintage gas and oil advertising. And for good reason: they were made to last, and they still do.
Why Sinclair Porcelain Signs Stand Out
Collectors don’t just want something that looks the part—they want the real deal, or something built the same way. That’s why porcelain enamel Sinclair signs remain top-tier. They’re not printed on aluminum. They’re not thin metal with stickers. They’re heavy, vibrant, and built for the elements.

Whether it's the classic Sinclair H-C Gasoline shield or the unforgettable DINO dinosaur sign, each piece tells a story of America's golden age of roadside service.
The Dino That Refused to Die
Sinclair first introduced the DINO mascot in the 1930s, capitalizing on the idea that oil was formed from prehistoric plant and animal matter. That quirky connection stuck, and the green dinosaur became one of the most enduring and recognizable symbols in American advertising.
You’d see DINO on:
-
Hanging curb signs with double-sided porcelain
-
Road maps, clocks, and even inflatable mascots at parades
But it’s the porcelain signs that collectors still chase. Durable, glossy, and bold—just like they were in the 1940s and ’50s.
Real Porcelain. Real Craftsmanship.
At Porcelain Handcrafts, we’re not just printing images on thin metal sheets. We’re doing it the right way—just like the signs Sinclair originally produced:
-
Kiln-fired porcelain enamel layered onto 1/4” heavy-gauge steel
-
Hand-punched mounting holes
-
Vivid, UV-resistant colors that won’t fade in the sun
-
Indoor or outdoor durability
-

Our Sinclair vintage-style reproductions feel like the ones you remember hanging at the station—or on the garage wall of someone who knew what quality looked like.
Final Thoughts: The Sign of a Better Time
The truth is, Sinclair signs aren’t just collectibles. They’re snapshots of a time when things were built better—when signs didn’t peel, colors didn’t fade, and brands made an effort to stand out. If you’re searching for a Sinclair gas sign for sale, make sure you’re getting one made like the originals.
Because when it comes to quality, the dinosaur still leads the pack.
