Blotter paper has been known for centuries as highly absorbent paper. It was used to absorb excess ink after writing, first with the quill and later with the fountain pen.

In the 1960s, the paper took on a completely new meaning: small, printed and perforated sheets, known as paper trips, became an iconic part of psychedelic culture.

LSD could be absorbed into the absorbent paper in liquid form, giving rise to the small stamps we know today as BlotterArt.

Amsterdam Blotter Classics were printed between 1980 and 2005 on authentic Old Dutch Blotter paper, continuing the tradition of printed and perforated blotting paper in Amsterdam.
