I know what you’re saying. In my day, it was Aubrey Beardsley. We found that in the proper state of mind, everything can be a baffling illusion. Look long enough at poster under black lighting and it was just like watching TV.
Or as my 19th Century Decorative Arts of Europe prof used to call him: Awfully Weirdsley. I liked Beardsley’s work, too. Had several of his books at one time, iirc. That was a good class.
