Needless to say, it’s primarily the homoerotics which concern us here. Gekko Hayashi is the name under which Japanese artist Goji Ishihara (1923–1997) produced his gay erotica, and these examples are among a small handful to be found on the web. Far more common is his Ishihara work which included some spectacular grotesqueries for the Illustrated Book of Japanese Monsters (1972) and the Illustrated Book of Hell (1975). Sate your appetite for the monstrous at Pink Tentacle.
Hayashi/Ishihara’s work may be scarce but you can read about both his personas thanks to ComiPress, who posted an overview of the artist’s career, and Comics212, who examined the gay side of his output. There is a book collection of Hayashi’s gay art but that appears to be out-of-print. This Japanese page has many samples from the Ishihara work.
The dual career of Hayashi/Ishihara brings to mind another artist equally adept at commercial illustration and gay art, Oliver Frey. As “Zack”, Frey gained an enthusiastic audience in UK gay mags while he was also popular with quite a different audience for his illustrations in computer game magazines throughout the 1980s. He was also no slouch at painting monsters as I recall. A collection of Zack comic strips, Bike Boy, is published this month by Bruno Gmünder.
