I believe you are referring to the Heritage Auction in which a memorial card happened to be inside the copy of the Warren Commission report being auctioned, that is, it wasn't part of the report. Note though that the size doesn't match the one you have found.From what I have found out is that this card was in a 888 page report by the commission presented to pres Johnson funny a pic of pres Johnson was in there to says that this card was handed out at private funeral session
