On the Beckett Marketplace website (I never use Beckett, only for finding out about cards), I found this-
This five-card hologram set from the Whitehall Collection, which measures the standard size, features hologram images created from actual photographs on the card fronts.
There are five cards, none are numbered, but what I read elsewhere are a set consisting of Babe Ruth, Ty Cobb, Cy Young, Honus Wagner, and Lou Gehrig.
Is this the ones you are referring to- http://www.ebay.com/itm/1992-WHITEHALL-LEGENDS-TO-LIFE-SET-Ty-Cobb-Babe-Ruth-Lou-Gehrig-Honus-Wagner-/110901460325
