Vintage Decker's Iowana Pork Sausage Sign NRA Rare Antique Store Display Sign. I have not seen another like this. Approximately 21 x 15 inches. This was a store display so not many were made. It has a sticker indicating that this is the first meat product poster produced from an actual direct color photograph. Also has a emblem from the National Rifle Association (NRA) with the eagle logo indicating We Do Our Part US. Beautiful graphics in color on this 1930's heavy card board advertising sign.
