I am sports artist Monty Sheldon and throughout 2009 I put up for auction my very first line of one-of-one, finished-penciled, sketch cards -  Sheldon's Sports Card Champions.  The set turned out to be the very first 1/1 sequentially numbered sports sketch card set in the hobby and consisted of 250 cards by years end. 
 
With the 2010 sketch card set I am at it again and this year I am re-introducing an old Pacific Coast League Zee-Nut card element--attached coupons!  Each card will come with a coupon attached at the bottom and after a collector saves varying amounts, they can be clipped and redeemed for other original art of mine such as sketch cards, hand-painted cards, baseballs, hockey pucks or cigar boxes. 
 
The 2010 coupon redemption plan is as follows:
 
10 coupons = One (1) 2010 S.S.C.C. sketch card which will be a part of the 2010 series; customer selects player
 
20 coupons = One (1) hand painted premium art card; customer selects player, more details to follow

30 coupons = One (1) hand-painted hockey puck or cigar box; customer selects player
 
40 coupons = One (1) hand-painted baseball customer selects player
 
Coupons distributed with the 2010 SSCC cards expire on 12/31/2012.

For those not familiar with the Zee-Nut card history, From 1911 to 1938, Collins-McCarty Company included their sports cards, highlighting Pacific Coast League baseball players, with their Home Run Kisses, Zee-Nut and Ruf-Nek candies. From 1913 to 1937 cards appeared with a coupon printed on the bottom that could have been redeemed for other items.
 
As I was signing a group of cards for the upcoming Topps National Chicle football and baseball sets, I noticed that the cards were the same size as the original 1935 Chicle football cards.  I really liked the look and feel of those cards and I decided that I would fashion my upcoming sketch card set to be roughly the same size.  After measuring the cards out on a blank sketch card, I noticed that I would have to trim about 5/8” off the bottom of each card.  Right away the similarities with the Zee-Nut cards hit me and the “sketch-card-with-coupon” idea was born.
