One thing I have always hated about college towns is the proliferation of community notices that make every cafe look like a laundromat.  The causes and events are always good but the effect is shoddy.  So we hit upon the idea of choosing posters for our own reasons  and blowing them up.  We use the architecture graphics firm, Service Point, 1000 Mass. Ave, near the former location of the old Orson Welles theater.  Service Point blows them up, to a size that I probably like because the dimensions are the same as a movie theater poster.   Right now we have handsome posters for the Boston Independent Film Festival and the Cambridge Science Festival/ MIT Museum.  You can’t miss them.
