Who the fuck would know that

you dont seem to. me too. so i´m asking.
people know tons of shit.

I would guess 1943

dont think so cause the 25 in the star is indicating that this blotter came out for 25th anniversary. that would be 1968, the year hippy development went big.

hmm i dunno, i've seen it dozens of times and never wondered who the artist was...

there is this guy marc mcloud. he has the worldwide biggest collection of blotter art.

i think it stands for lsd-25

>>2354241
i think it means that there are 25 tabs.

>>2354392
there are sheets of paper which are bigger, 100 tabs for example. and they still have the 25 on it.
and on the newer ones with the 2000 on the bottom instead of 1943 it also says 25 so i think this

is right.

could be an interesting graphic designy series, blotter art, might put that on my list of projects to whittle down
