Just want to throw these plates in the mix, " USA-1 " with " Chevrolet " stamped below. Bought these at an auction last year and had never seen them before. Did a little on line Google search and found they were originally offered in 1957 by Chevrolet and were know as " booster plates ". Steel plates which are standard size with today's plates. Kept one for my 57 and sold the other three on a tri-five board I am on. Bit of an intersting read if one cares to Google search these plates. I kept the black with white lettering for my 57 front bumper.
