SAMPLES from this set in the scan. BUT the NAMED PLAYER ONLY. From a set of 20 unnumbered light card stock 2" by 2" square proofs.
Below the player name is 'M.L.B.P.A. Baseball Buttons Vincentown, N.J. © 1992'. Backs are blank. Numbers assigned in alphabetical order.

Listed in the Beckett Guides as '1992 Carol Wright Proofs'. With the statement, These 'proofs' were issued by Carol Wright to promote their products. Each of these proofs were issued to a stated print run of 1500 sets.
I believe Beckett will be updating their set notation for this issue. Changing from 'Carol Wright' to 'Vincentown Button' proofs.

Carol Wright gifts is a still active catalog mail order company that offers personal care, household, apparel and sundry inexpensive products. I do not understand why a baseball set issue would have been a 'big deal' to their customers? I doubt that many made it into the hands of any hobby sources. Most likely those sent with orders would have been lost or tossed by housewives more concerned with their 'health' products. So...TOUGH! to find.

Not currently listed by Beckett is a second set of 20 PITCHERS only. The same format as the 'hitters' issue except colors are reversed, yellow at the top and red at the bottom.
The Pitchers set - Jim Abbott, Steve Avery, Tom Browning, Roger Clemens, Mark Davis, Rob Dibble, Doug Drabek, Dwight Gooden, Orel Hershiser, Bruce Hurst, Ramon Martinez, Jack McDowell, Jack Morris, Charles Nagy, Dan Plesac, Jose Rijo, Nolan Ryan, Lee Smith, Rick Sutcliffe and Frank Viola.
