Handler studied in numerous disciplines (and has a BA from SUNY-Purchase in Art History). You can see more about his background and raisin d' etre at the website above (or at his website HERE). This piece has the childlike exubrance of much of his work but it is sedate in comparison. There is something frenetic and wild in the pieces you will see at his website.
Kahn is, of course, Kahn. He is one of the world's greatest living painters.
