The Gilmore gas sign seen most often shows a circular yellow field with a leaping lion in red in the upper part of the circle. Below this is "Roar With Gilmore," first two words in black and Gilmore in red. A checkered racing flag is at the bottom. A variation shows the yellow field outlined in red.
Another Gilmore gas sign shows a yellow circle with "Gilmore Gasoline" in red and "Blu-Green" in green. Inside this is a white circle with a front view of a lion's head.
A third sign shows a rectangular red field with "New and Improved Premium Oil" in yellow. There's a diagonal yellow band with "Lion Head" in black and a front view of a lion's head between the words.
