Vintage 1960s Schmidt’s The Easy Beer Paper Bar Coasters Set of 4 Philadelphia

Lot of 4 vintage Schmidt’s beer double-sided paper coasters featuring a coat of arms theme. C. Schmidt & Sons, Inc., Philadelphia, PA. There is no date printed but I believe these coasters date from the 1960s. Both sides of the coaster have the same design with the tagline “The E-E-E-Easy Beer”. Condition is good. The coasters appear unused. Please zoom all photos for more details. Each coaster measures approximately 3-3/8 inches square.
