Unfortunately wasn't old enough to go to these back then. But when I look back now as someone legal aged to go out clubbing and partying, I kinda wished I was there for those days, they just seemed a lot better than what we got today. Not to say today's standards of clubbing is bad, but I feel back then would have been better.
This drawing looks a lot like what I would see for highschool rave advertisements from students being pasted around the school in some 2000s highschool film.
