This scarce card is one in a series of  cards issued  by  the E. ROSEN Company of Providence Rhode Island.  Although no guide I know of provides an exact year of issue the consensus seems to be that they were issued sometime during the 1930s. the E. Rosen company was a producer of Candies during this time and although no product is mentioned on the card, it is believe to have been given away with their brands of Candy.  The series is designated  as series R139  in Burdick’s  American Card Catalogue and is entitled “Soldier Cards”  Although on the back of the card it does list the series as having 192 different cards in the set.  No number higher than 36 has ever been recorded so it is believe that the series is complete at 36 card.   The  front features an illustration of a soldier from a different nation.  The back features a description of the featured soldier and the card number in the set.  This card is #4 in the series and features a Russian Cossack soldier

 The Card  measures 2 3/8 inches by 2 7/8 inches approximately .  The card does have some creasing and an area of discoloration. I have scanned the front and back of the card fairly large so you can determine the condition for yourself.
