Following a successful debut last year, The Stray Show, an ad-hoc art fair in Chicago catering to artist-run exhibit spaces, is expanding. This year, Stray (which is organized by Thomas Blackman Associates, who bring us ArtChicago and the San Francisco shebang), will present stuff from 50 arts organizations from all over the country. Representing Texas will be San Antonio’s Sala Diaz and The Bower. The exhibition will take place December 13 – 15.
