Super Art Gocoo magazine - July 1980 issue / an interesting magazine published in the late 70s and 80s by Parco Gallery in Tokyo. Every issue has multiple illustration galleries, often with airbrush style work & graphic design and illustration legends (Kiyoshi Awazu, Tadanori Yokoo, Aquirax Uno), plus music features and articles in Japanese. (Lots of fashion photos and illustrations in this one.) The ads are often great too -- for stuff like keyboards and laseriums / used copy in OK condition (complete but with the usual age wear of scrapes and spots and toning)
