Blotter art originated in the 1960s when acid dealers sought to differentiate and brand their products, leading to the creation of beautifully designed blotter sheets that emerged as art and entered the market. The choice of this perforated paper, the blotter sheet, as a medium was also influenced by the regulations of American law at the time. After 1970, the legal hobby of collecting unused blotter "art" flourished, and the artwork became even more sophisticated. In the 80s, a private museum of blotter art called III was established in San Francisco. Today, blotter art is collected as a field of applied art. Perfect for gifts or collections! Originally printed with vegetable ink on blotter paper (blotter sheets) designed to absorb psychedelics, and perforated. The perforations also have their own unique characteristics, providing clues to identify each creator. From various perspectives, blotter art is now an established art form with collectors worldwide.
