thanks for the kind words! check out Jamie's thread "show us your ghosts Halloween"....steve posted the "gilbert"......in regards to the clear impressioned black inked outlined card such as weimer, gilbert, chance there must have been a sheet that was factory cut, except,( tim c can explain more), with a cylindrical print that reversed printed these and was fact cut, and 1 sheet escaped or 2.....there are only 12 or so examples out there.....on rarity of brown old mill and, imho, just as cool


.....
wst and overprints or "impressions" are different in that wst were simply wet ink that was stacked from another card(blurry, not clear).....
where as "cylindrical impressions" and "overprints" were caused by the striking of the actual printing plate to the cardboard, or , as in the case with the cylindrical ones, were caused by the "rollers" if you will, not being thoroughly cleaned, applying ink to the cardboard thru machinery...
big difference in price and rarity...
Weimer.....8-10 k card....
wst- a few hundred
steve b, tim c, jim , chris b can chime in with more
