Hello All_
i have a phillipe with a similiar "print mark" in the top border....its a terrible scan, but also part 2 namer....i bought off ebay for like 60 bucks...i mainly collect t206 "freaks" and saw this example, said what the hell....they are a bit rarer than expected, but nothing real "exciting"....
there are some "printers crop marks" on some t206 backs, they are a bit tougher...theory- these marks where placed on sheets to align them for dicing....some of my examples are oddly cut which show parts/full crop marks on the backs....i have scanned ebay over the years and they occasionally pop up, but are tuff 2 find

to each his own, i place a primuim cause of there "rareness" but nothing crazy sweet like printers scrap

all in all they are fun and unique...these examples are noteworthy tho...
as for matty proof....that is in a league of it's own and deserves a new thread devoted to it!! Leon!!LOL!!as u know, printers scrap is different than production t206..big differences..
Peace
Johnny
