Threshold is a black-and-white comic book series in anthology format published by Avatar Press. Its website describes it as "an ongoing comic book series published four to six times a year", but since January 2006 after Issue #54 it has apparently stopped publication. The book consists of three to six stories per issue. Launched in 1998, Threshold had become the premiere anthology on the independent comics scene--and the longest-running American anthology comic title in the direct market, 2000 AD being a British publication. A title that has been called the American indy scene's answer to some of the world's best-known comics anthologies such as Heavy Metal and others, Threshold has encompassed a huge variety of stories for the mature readership including horror, science fiction, sword and sorcery, jungle fantasy, erotica, adventure, manga, and more. Threshold has featured characters and titles such as Pandora, The Ravening, Webwitch, Lookers, the Furies, Fauna, Faust/777, Razor, Widow, Snowman, Nira X, Kaos Moon, Cuda, Dark Blue, and dozens of others by creators such as Warren Ellis, Tim Vigil, David Quinn, Mike Wolfer, Al Rio, Jacen Burrows, Matt Martin, Sean Shaw, Rick Lyon, Bill Maus, Matt Martin, David Boller, Phil Xavier, Robert Lugibihl, and many, many more. Many of the 54 issues posted include multiple variant covers.
