The non round sign is a two sided neon version. The 5 foot diameter signs originally came with a black painted outer ring and attachments for attaching to a pole or building plus lighting from above the sign. There was also a neon version with amber yellow "service", blue "approved" and the outside border in red. Apparently all dealers got the round sign for display and they cost $62.50 from Reliance Advertising Co. in Chicago. The various neon signs were optional at extra cost. There were at least three booklets about ordering K-F Signs and many styles of neon signs and outdoor reflectorized road signs were available. The red, white and blue Kaiser Willys signs started to appear in 1953 when Willys was absorbed into Kaiser. Maybe someone has a picture of the two piece Kaiser sign with Willys at the bottom that Jim has seen and that will answer the question of why they made some of the signs in two pieces.
