This listing is for a 2017 Bowman Mega Box #BCP31 Shohei Ohtani that has been graded by CGC as Authentic Altered.  I bought this card when it was slabbed by BGS as an 8.5 and decided to crack it and get it slabbed by CGC hoping to get at least a 9.  I made no alterations to it, I merely cracked it from slab, put it in a soft sleeve and semi rigid holder and mailed it in to CGC, so I was very surprised when it came back Altered.  They indicate the right front edge shows signs of Alteration.  I have included a picture of the BGS 8.5 label and of the paper that CGC included with the card when they sent it back to me.  Please feel free to ask any questions and be sure and check out my other listings.
