Another possible minor paper fold error on a 5 1/2 Rouletted RB23 with "Shifted Perforation
". Albeit not our classic paper fold error with blatant unprinted "white" areas but it does appear to be a crease in the paper just at the beginning of a possible double/triple fold that would have gone down the paper sheet (plate). Or was this caused by being affixed to an uneven package surface?
I need to hunt around and see if I can find other examples, with the same company print cancellation, but further down the plate which would display a more pronounced folding error if it is indeed a fold error.
