My Helsinki through May 31st looks intriguing; although, since I’ve been traveling, I’m not sure I’ll be able to see it, except for this weekend. I like the concept of cast off treasures becoming “Everyday Monuments” by Jean Shin as part of the Common Threads exhibit at the Smithsonian American Art Museum. Her “Chance City” comprised of lottery tickets as a House of Cards, changes daily as onlookers walk by it and cards fall. It runs through July 26th.
