I see that the Chicago Photographic Collectors Society photo and image show is on May 4. http://www.chicagophotographic.org/shows.shtml I haven't been to one of these in a while. Pre-internet they were large and crowded shows. The last one I went to a few years back seemed a lot smaller. I may go. The entry fee is for a good cause and if the show is small and things expensive I'll be able to complain about how it was so much better in the past.
