Back in 1999 Upper Deck released a set called SP Signature which featured 1 autograph card per pack. Each pack had either a base auto, or a gold parallel /50 (for many of the cards.) Beyond this there was a small 8 card insert set called "Legendary Cuts." These cards featured an autograph of a deceased player. UD was able to do this by cutting an autograph from another document and inserting it into the cards. To the best of my knowledge this set (or possibly it's partner which was inserted in 1999 Upper Deck Legends) were the first cut autograph set.
In the process of looking through some old auction results I came across some scans of a couple of these. The Lefty Grove is currently on eBay (with an insane $3750 BIN) so I pulled that scan from there.
I thought it would be cool to share these images, and thought that will a team effort we may be able to gather all the scans.
