I've received a bag and board taped like that before ... at least I think it was cat hair
I forget who it was, but one board member would give out negatives on Ebay if someone had hair on the tape they used because he was so disgusted by such things.
Note to self - wear hair bonnet when packing comics.
Note to self, also wear a apron, I'm a little chest hairish.
I've got two dogs, and now that it's summer they are shedding like crazy. Every single one of my packages that I send out has some dog hair. Haven't gotten any weird feedback on that yet.
