Got an e-mail from Susan (long time listerner, first time caller) that she saw a listing on Amazon for "Shag: Art of Josh Agle Postcard Book" from Chronicle Books (ISBN: 0811851869 ).

Some sites list the release date as June 2006, some say April. Looking at the Chronicle Books site, the other postcard books they're selling for $9.95 have 30 postcards (perfect for you "mini-print" dealers).
