Every TRU sticker that I've removed from an MOC item has been pointing straight up and down on the card, with the information at a right angle to the rest of the card.
None of these stickers have revealed any surprise damage below.
There are a lot of MOC items I'm coming across on eBay where the TRU sticker (or stickers) is at a weird angle. And sometimes if there's more than one they're sloppily overlapped.
This seems weird given the items I've personally come in contact with.
Does anyone have any thoughts as to whether the angle of the TRU sticker is any indication of authenticity?
