You might try contacting The Wolfsonian in Miami Beach, FL.  It's a new
museum with a collection specializing in Michell Wolfson Jr's decorative
and propagana arts.  The have an exhibition opening this weekend (I
think) called "The Arts of Reform and Persuasion 1885-1945."  They are
located at:

1001 Washington Ave.
Miami Beach, FL  33139
(305) 531-1001
