wow this seems unreasonable by CGC to deem something you bought in good faith off a newsstand was not what you were actually paying the money to the seller for, non suspecting you were actually being ripped off by retailer, mask should have been stapled to comic. If you want to be pedantic about this please see consumer laws in Britain it might help answer this issue debate with loose missing mask, I'm not 100 percent sure I'm right but something about this type of customers and consumer rights when you buy something new of a retailer ( no matter which retailer ) you expect for it to be complete and untouched, by what CGC are suggesting there may have been foul play somewhere, so someone should take the onus for that, not the poor comic owner who now holds an incomplete issue ( loose mask placed inside of pages, missing! ) so gets a black mark (so to speak) against his future selling of this comic at the right grade for the correct price. seems iffy to me mate check it out. sorry bout that i get worked up sometimes over them lording it over others who are actually just human beings like the rest of us except they're probably more minted than most hmmf
