GFA stands for "Glamfur Archive"! This site is dedicated to archiving art from an almost forgotten period of the internet. Glamfur was a stylistic movement within the furry fandom that inspired a lot of modern furry substyles within the community. Such substyles include; Sparkledogs, Gloomdogs, Scenedogs, Ravefur, and a lot of the darker (+ brighter) artstyles adopted by the furry community.
Glamfur is a very bold and noticable style, a lot of the art has very distinct features as well as bright and edgier color schemes. There have been several talented and notable artists that have adopted this style, but as time has progressed, the number of people using it has dwindled. Sites like DeviantArt, FurAffinity, e621, LiveJournal, and others were a haven for this art movement to flourish. As of recently, there has been a slight spark in revival in communities such as Twitter, Tumblr, and Instagram.
The GFA started when the moderator, Mika, had stumbled upon a random DeviantArt comment suggesting his style reminded them of Glamfur art. Curiosity led him down a rabbit hole, and now he runs a huge archive of Glamfur art.
