Are you the arch-enemy of all that is good and decent, and also happen to be the fearsome leader of a mysterious international cartel? Do you need a logo? As long as your nefarious organization is called F.I.S.T., then please feel free to use this logo I have just designed. Your cadre of evil lawyers can probably win the lawsuit required to register this piece.
I thought it would turn out better, but since it's just a quick concept I don't feel the need to substantially improve it, either.
The artwork is based on a clenched-fist logo used by Howard Stern in 2005. In turn, his art department likely copied the famous Berkeley protest fist woodcut designed by Frank Cieciorka in 1965.
