X-magazine Jam was launched in 1979 and is part of Japanese subculture history. It was sold as a vending-machine magazine and only 10 issues were published.
After Jam ceased publication, a new subculture magazine appeared, the legendary Heaven (designed by Heikichi Harata and Shin Sobue)
This is the sixth issue of Jam, edited by Takanori Takasugi.
A hard to find and chaotic magazine, a mix of eroticism and subculture
