2 Orig. Vintage Beer Pinbacks-KAIER'S-PILSNER NATIONAL

These 2 original vintage beer advertising pinbacks are at least from the 1950s, maybe earlier. One advertises NATIONAL PREMIUM...THE TRUE PILSNER and has the Mr. Pilsner logo in the center...marked National Brewing Co. - Baltimore Md. on the rim. The other says...WE SERVE KAIER'S SPECIAL BEER-ALE-PORTER....Kaier Brewing Co. - Mahonoy City, Pa. These pins measure 1 1/4 inches across and are both in excellent condition.
