It is large, measure 29 in diameter, and has retained its very vivid colors. Date of origin is unknown since there is very little information I could find on Google. My guess is sometime in the 1960s and it was manufactured by Press Sign Co.It appears that is was produced by Dads Root Beer out of Chicago, IL. The sign is in very good condition overall, having some surface rust, some scratches and light wear in areas(see photos).
