I managed to obtain all the 10 cards from the NFL 1997 PETER MAX special artwork, plus the uncommon SUPER BOWL XXX poster (signed and dedicated), and I assembled all into one huge framed piece. I did the same a few months ago with the Baseball series. I am pretty sure these sets are unique in the whole world.
