Gretz Beer empty flat top beer can by the William Gretz Brewing Co., Philadelphia, PA. The brewery operated from 1933-1960, and the beer that was in this can brewed about 1956. Car series, Mercedes-Benz; air-sealed; sharp colors; clean top lid, nominal markings on seam & bottom lid; few scattered markings on body of can, the worst shown in the last close-up picture. An example is pictured on page 75-21 of the USBC book. Bidding begins at a modest $220 and shipping is free to ...anywhere within the United States. This would make an ideal holiday gift for that special beer can collector. Thanks for Looking!!!!!!!!!
