This is a 1997 Leaf Signature auto card of   Yatil Green

It measures 8x10 inches, all the cards in this set were this size.  This is the signed/autographed card from the set. It says authentic signature and should be signed on the bottom.  A few cards the player signed in the upper portion. 

These were unnumbered and listed alphabetically.  The number given is from a checklist I found.

The condition is at least NM.  There may be some white showing along the edges and corners.  There are no bends or creases. These are ideal for framing or plaques. The scan should be a good judge of any imperfections.
