The annual Pilsen Artists' Open House (otherwise known as "the Art Walk") is taking place this weekend, and, as usual, the work runs the gamut. Put another way, there's something for everyone. Gallery no. 23 is hidden from view at the top of a rather foreboding set of stairs, but Jeremy Ehly and Kate Dougherty both display interesting and, at times, amusing points of view. Dougherty illustrates her photos with cartoonish embellishment, while Ehly's series elucidate the patterns in architectural elements like corners and cornices and tease out the humor of real estate marketing with tounge-in-cheek titles for images of residential monoliths. In other words, three flights up won't kill you.
