This artist illustrated for Japanese magazine Uramado meaning Rear window, “Rear glasses” in French (or “Window on Court”, according to the French title of the film from Hitchcock).

Unlike “Soshi” who was content with a copied glue from Kitan Club, “Uramado” was doing well by illustrations of great qualities, daring, sometimes using collage, or mixing several graphic methods at the same time.

I was unable to find info for the artist.
