Issued in 1910 by the Texas Gum Company, the E105 series was a 50-card set that shares its checklist with the E92 series of cards, with an attractive, green ad on the reverse. Printed on unusually thin paper stock, it is theorized that many of the cards were folded vertically so that they could be inserted into the gum packs.  Many of the surviving examples are found with horizontal creases down the center. The cards are particularly scarce today, and are quite a condition rarity as well.

This example features Doc Casey, a bright and colorful card, graded POOR 1 by PSA due to the horizontal crease. The card boasts unusually large top and bottom borders, and the desirable Mello-Mint ad on the reverse is clean and entirely visible.  A truly difficult card.
