Blotter art originated in the 1960s when acid dealers sought to differentiate and highlight their products from competitors, leading to the branding of beautiful blotter sheets as art, which then began to circulate in the market. The choice of this printed, perforated paper, the blotter sheet, as a medium was 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. How about it as a gift or for your collection?
