For many years, these Blue Tint cards were identified as 1947, or 1947-1948, or 1948-1949. And, in some instances they still are.
They are strictly a 1948 issue....period.
Also, their ACC classification....R346....is incorrect. These cards were available in strips of eight. But, they were never associated
with any gum or candy products. Therefore, they should have been classified as a W-xxx issue.
