Cool S

The Cool S, also known as the Universal S, the Stüssy S, the Super S, the Pointy S, the Banksy S, the Surfer’s S, and the Graffiti S, is a graffiti sign in popular culture and childlore that is typically doodled on children's notebooks or graffitied on walls. The exact origin of the Cool S is unknown, but it became prevalent around the early 1970s as a part of graffiti culture.

Shape
The Cool S consists of 14 line segments, forming a stylized, pointed S-shape. It has also been compared to the infinity symbol. The tails (pointy ends) of the S appear to link underneath so that it loops around on itself in the same way as the infinity symbol does. The Cool S has no reflection symmetry, but has 2-fold rotational symmetry.

History
The exact origin of the symbol is unclear, but it is generally considered to be an artifact of childlore, meaning that it is taught by children to children, over the course of generations.

Jon Naar's photographs of graffiti in New York City, which were taken in 1973 and published in The Faith of Graffiti in 1974, feature the symbol numerous times, identical to its modern form. Jean-Michel Basquiat's artworks also occasionally have the symbol hidden somewhere, such as in Charles the First, and in the one titled Olive Oil from 1982 it is labelled as the "classic S of graff".

The name "Superman S" comes from a belief that it was a symbol for Superman, whose costume features a stylized S in a diamond shape, but that shape is quite different. Emmy Coats (who has worked alongside Shawn Stussy since 1985) has stated that it was never a symbol of Stussy's Californian surf company. In 2010, the company uploaded a video to Vimeo and later to YouTube in which one of Jon Naar's 1973 photographs of the symbol can be seen.

The symbol was trademarked in the United States in July 2020, but Mark May, the trademark owner, says he does not wish to own the trademark for financial reasons but rather "to preserve it [...] and to truly revel in its irreverence".
