| Issued by the E. LEVERING COFFEE Co. of Baltimore Maryland U.S.A, as an insert premium with each package of their brands of coffee. The series is titled "Flags of the Principle Nations of the World", and is listed in Burdick's American Card Catalogue (ACC), as series K137 I have not been able to find a listed date of issue for this series but I speculate that it must have been sometime during the 1890's. The front of each card features a colorful image representative of the featured counties National Flag, while the back lists the other flags represented in the series and features advertising for Leverings products. The Card measures 4 1/2 inches by 2 3/4 inches approximately. | ||
