This one is a favourite of mine. The colours are really explicit,
leaving no doubt about it's function. It was produced in the late
80's, reflecting how people at that time were "busy bees", flying
from here to there, wanting everything to be as efficient as
possible. If someone felt like vomiting, a glance at this bag would be
enough to trig the right muscles in the neck/throat region.
I also like the way this bag not discretely mentions what to do with it after use, but instead loudly advertises what to do with it, inside the tagged area in the bottom right corner, which looks more like a field you would expect to say "SALE! Special prices!" or something.
