In Washington DC an artist group held art shows called "Art-O-Matic" because the shows were held in an old Washing store called Washomatic. I participated in the yearly shows and wore a different  dinner jacket every year and had participants autograph my jacket.  I aways gave the jacket to our group except for the last show in which I participatedin in 2007. Looking at the jacket last month I noticed it was signed by Frank Warren (first name only) and the words "Post Secret".  Since then Frank has gained world-wide fame with his creation with books, web site and personal presentations..
