While supplies last, Professional Sports Authenticator (www.PSAcard.com) will give away free "Evolution of the Baseball Card" posters at the 2015 National Sports Collectors Convention.

The 24 by 36 inch full-color posters depict 18 PSA-certified baseball cards dating from an 1887 Old Judge Cap Anson to an autographed 2014 Bowman Chrome Kris Bryant card.

Other cards illustrated on the posters include T206 Honus Wagner, 1915 Cracker Jack Joe Jackson, 1933 Goudey Babe Ruth, 1952 Topps Mickey Mantle and 2001 Finest Autographs Albert Pujols signed card, all featured in PSA holders.

"Baseball cards have gone through a visual and technological revolution.  The poster provides a vivid sampling of some of the iconic cards that have captivated collectors for generations," said PSA President Joe Orlando.

As announced earlier, PSA will hold daily sweepstakes at the show for prizes related to three of the top players in the history of the Chicago Bulls, Chicago Cubs and Chicago Bears, respectively.

"We'll give away a 1986 Fleer Michael Jordan rookie card graded PSA Mint 9 that is now valued at more than $3,000, an autographed Ernie Banks baseball bat and an autographed Walter Payton poster," said Orlando.

Visitors to the PSA booth (Hall B, #1436) can register for the sweepstakes, which will be held during the three middle days of the show.  There is no cost to enter, and the winners do not need to be present at the time of the drawings.

The 2015 National (www.nsccshow.com) will be held July 29 - August 2 in the Donald E. Stephens Convention Center in the Chicago suburb of Rosemont, Illinois.
