There were several movies that came out in the early 70's that apparently were designed to make the audience puke. They started a trend: when you got your tickets they handed you barf bags.
I cant remember any of the titles off hand. One was about the torture used in the middle ages, others were slasher films.
I never went to see any of them, but a few of my friends did. Ill bet if you saved those barf bags you could sell them now on ebay for a lot of $$$.
OK: Google is my friend today. one was called 'mark of the devil'
EDIT: I found a less,umm... objectional review of the movie:
