This multi-layered glass self-portrait of Japanese artist Keiichi Tanaami is a limited-edition reproduction of an original 1960s piece. Upon each pane of glass is impressed a single colour and single pattern so that when the panes are aligned a coherent image can be seen. The three dimensional play of light and colour as one’s eye moves across the work evokes Tanaami’s psychedelic background as well as the youthful verve of his days as Art Editor of Japanese Playboy.

Only 20 editions of this artwork were made. This piece costs Yen 42,000 (£181) inclusive of tax from here.
