American Comics Group

American Comics Group was an American comic book publisher that operated from 1943 to 1967. ACG published the medium's first ongoing horror comics title, Adventures into the Unknown. The company's best-known character was Herbie Popnecker, a 1960s satirical-humor hero who starred in Forbidden Worlds and later received his own title as the superhero Fat Fury.

Founded by Benjamin W. Sangor, ACG was co-owned by Fred Iger from 1948 to 1967. Iger's father-in-law Harry Donenfeld, head of National Periodical Publications (later DC Comics), was also a co-owner in the early 1960s.
