Just received a couple little plastic travel bottles from the 80s (on AS and one cologne). The AS smells a little sharper than what I'm used too and I don't know if maybe that's because of being stored in plastic (I've seen a few people who seem to believe there is a difference). Anyway, do you think there would be any danger in mixing different batches of the vintage AS? I wouldn't want to ruin what I have on hand.
