Hi, Gang. Wondering what the value might be on this painted tin, WILLARD Starting Service flange sign. It measures 18" by 22". This photo shows the best side. Has some neat graphics. There's a little paint loss in the red at the very top.

From the design of the car shown, I'm thinking this sign is late 1930's in vintage. Thanks for any thoughts on this. John
