Chagall, "The Poet". Remember seeing this in Minneapolis Art Institute. Wrote a poem about it once back in 70s on a manual typewriter. Haven't been able to find the poem for a long vremya.
p.s. 5.22.07 : still haven't located that early poem. I wanted to send it to the Art Institute to see if they could use it for a poster. This may be a task for future scholars : find Henry's lost poem about Chagall's "The Poet"!
