John

,
You have a great point! (about the anomalies, i'm just biased

)!!
definitely something of a "fringe" type thing.....just no boundaries, they would have to be basic generalities(ie just split back, crop mark, sheet #, upside down, ), more unique collector(like you and me)......
i love the way you split the master set, thats a great way to look at it....and John, thanks for leaving off Cobb
Brown om are almost like an enigma to themselves, and i think could go either way....i have been more of the freak collector, Craig, Tim, Art, Dan, Jim, and so many others are fine tuned on the scarcity, i wish i just bought more back in the day, im kinda out

....but scanning ebay for umpteen hours and auctions just some observations...
John,
I LOVE THIS POST!!
Peace
Johnny
