Secondly, about the greytones being in Fine condition and now are wall books, this has been true for a bit, from what I've seen as well. Rarely, will you find one of those higher than a Fine. In my opinion, they should all be wall books, but every dealer has a limited amount of wall space and with the majority of buyers wanting men in tights, there just isn't enough room for the greytones. Start finding those beauties in F/VF and above and you've just hit the jackpot, tiger.
