Mamekyu, a Japanese artist from the bygone era of AR. It used to be one of the only Artists online who did AR. I don't think anyone knows what's happened to him, as any new art generally stopped in the early 2000s. Hope that helps.
It's from an artist called "Mamekyu" who is/was a Japanese AR artist. His work used to be featured on the ararchive, or "2 be young again," but has since been taken down. I'm not sure where it's stored now.
