Set of 4 vintage Pla-mor bingo cards

Such a cool vintage find. Sold as a set of 4. Made in the USA. Little red plastic doors slide over numbers when they are called so that they can be used again and again. All bingo boards have appropriate wear for vintage games. There are dinner marks and scribbles on all which I think adds to their charm. More sets available in my closet. 8.5x7.5
