The cards have no numbers on the back and were designated numbers to be cataloged by player, in alphabetical order. The Irving Lewis card is designated card number 102, and might show up in some catalogs as card 105.
The Irving Lewis card is one of three rarest cards out of the T207 Brown background set. The other two being Ward Miller of the Cubs and Louis Lowdermilk of the Cardinals. There are two variations of the Lewis card; one with the Braves insignia on his sleeve (102b), and the other card (the more rare) the sleeve is blank (102a).
The back of the cards might have different colored printing depending on the tobacco endorsement which includes; Napoleon, and Recruit little Cigars, Broadleaf, and Cycle Cigarettes. A 1980's reproduction of the card was made with the history of the card printed on the back, and has little value. The card also states a value of $700. (the value of the card in the 1980's)
The current value is about $2,000.-$5,000. in excellent condition, depending on the variation, and cards in better condition could sell for more accordingly. It is difficult to get a more accurate value because of it's rarity, their appearance in auction are rare as well.
I could not find a recent auction for the Lewis card but did find a 2006 auction for one of the other three cards that are rare. The T207 Louis Lowdermilk card sold for 5,800.00, and the card was Estimated to sell for $2,000 -$3,000.
