Ted, for whatever reason Burdick categorized most 1930-s and 40's sets as R-cards. Many were sold in the same manner as these, a baseball example is the Eclipse Import set (R337)--is there any evidence that Candy was associated with those? How about MP & Co sets (R302), these also were sold in strips. There are tons of nonsport card examples as well... (here are just a few of them from the nonsports side)

If these were a 1920's issue they would almost certainly have been a W-set but for whatever reason they weren't really consistent with the 30's and 40's cards and whether they were R's vs. W's.
