Error card - 1988 Fleer Update #U-93 Kirk Gibson.

Look at the letter "U".  It looks like there was an error in the printing process and the U was incomplete.  I have not seen any other cards with this error so could be a one of a kind!

Please ask any questions or for more pictures before purchasing as card is sold as is with no returns.  I can provide additional closeups and scan for a more high res picture if youd like.
