The holographic set is commissioned through Lime Rock International Inc. The holographic set is a Signature Series Issue 2- May 92.

The inside of the display folder for the holographic set is not signed though. I am wanting to know what the appraisal value is for the holograpic set as well as the appraisal value for each card in the collage of cards. The collage of cards has 1 Mother's Cookies card of Ken Griffey Jr. which is #1 of 4 and 1 Mother's Cookies card of Ken Griffey Sr. which is #2 of 4. The copyright date for these Mother's Cookies is 1991. I was wanting to know if the player or the receiver of the Mother's Cookies cards was suppossed to sign the autograph spot? The Mother's Cookies cards have remained unopened. There is also a Holo #2 Ken Griffey Jr. card that is a Special Collectors Edition produced by Arena Holograms, Inc. with a copyright of 1991 and is a Limited Edition of 250,000. The purple Ken Griffey card is produced by The Topps Company and has a copyright of 1990. The Front of this card has Kaybee Kings on it.
