Sinclair Green Dino Large Die Cut Porcelain Enamel Sign

Few symbols in American petroliana are as recognizable as the Sinclair dinosaur. Introduced in the 1930s and popularized at the 1939 New York World’s Fair, the green Brontosaurus became a lasting emblem of Sinclair gasoline. For decades, it stood along highways and service stations, representing dependable fuel during the golden age of American road travel.

This left-facing Sinclair Dino sign captures that classic roadside presence in true porcelain enamel on steel. Built the way original gas station signage was made — heavy, kiln-fired, and glass-smooth — it delivers the depth, gloss, and visual weight collectors expect from authentic porcelain.

Available in 42" and 54" sizes only.

Authentic Porcelain Construction

Each sign is produced using traditional porcelain enamel methods — powdered glass fused directly to steel at high temperature. The result is a smooth, glass-like surface with rich green color and permanent durability. This is not printed metal or a decal application; the enamel is fired into the steel.

At 42” and especially 54”, this piece approaches the scale and impact of original station display signage. It functions as a true focal point in a garage, showroom, or curated petroliana collection. Few images command attention like a full-scale Sinclair Dino mounted on a wall.

For collectors building a serious Sinclair display or classic gas station theme, larger-format porcelain makes the difference.
