Scott, I hear you on the multi add backs and if it was just the Young ghost I think it would be more visually appealing. For me the ghost and brown OM combo are killer. If I had 100k, I'd put down 15-20 for the ghost and pass on the Matty as I've got no clue on these first run proofs. Either way, beautiful cards and both one of a kind.
I'm hoping we can get some high res scans of the Mullany. I would love to "rebuild" it in photoshop to see all the different print layers.
