Paul First Thank you for sharing your cards. I do know that a number of Ruth R309's have original envelopes. So my thought was if we could get some postmark dates from the Ruth envelopes And find one with a 1935 date then it could be said with certainty that the same card was used for both sets.
Great thread for a guy like me who has always loved all the candy and Gum cards from the 1930's ( R300's ). And the Sports Kings Premiums are among the least understood and rarest of all pre war cards.
