If you’ve ever taken LSD before you’ll probably have a great deal of respect for the power of those tiny little pieces of printed, perforated cardboard. If not, they’re still pretty cool to look at. Mark McCloud has compiled a history of LSD blotter art in this tiny book, and with Christmas coming up it’s the perfect gift for those friends/family members who can even look at a tab without facing a sense of sheer panic.
