Art note

On a recent trip to New York I spent an hour or so in the (very crowded) Guggenheim museum and was especially taken with one painting in the exhibit on abstraction in the '20s and '30s, namely Jean Hélion's Composition (April-May 1934). I just glanced at the Wikipedia article on him, which I found interesting because I knew nothing about him. A main point is that he began as an abstract painter but didn't remain one. I'm not familiar with his work beyond the one painting I just mentioned.
