The word "CAS", "Cardinal, and "Auto Sales" is in a stylized font with the letter "A" in "CAS" in the shape of a triangle with a small right slanted opening in the bottom left corner. A small image of a bird, specifically a cardinal, is affixed above the top right corner of the word "CAS" as if it is perched/standing on the letter "S" and is facing left.
