Julie Svendsen was kind enough to send me recently this 1987 Christmas card by John Hench.  According to Julie:

[Here's the cast of audience characters:  starting from the left, that's Matisse cutting the paper; Dali; Toulouse Lautrec in the bowler hat; John Hench wearing the Mickey Mouse shirt; one of John's pet cats; Lowry, John's wife; I'm guessing Amedeo Modigliani (pulling the little nude lady toy); Picasso in the striped shirt; Chagall with the white dove.

There's a person peeking out from behind the curtain and I don't know who that is.

The puppet show characters are: Arlequin; Polichinelle; and the other pet cat of John's.]
