If you’re local, perhaps you’ve seen some of these images on buildings around town. I found out about them the same way I find out about everything else lately: Instagram. Done by the director and co-founder of Chalk Riot, Chelsea Ritter-Soronen, the murals were created to raise awareness for the Syrian refugee crisis. She has secured 12 locations around St. Louis on which to put her wheatpaste images. Wheatpastes are made out of a glue consisting of flour and water, with an end result kind of resembling thick butcher paper. Unlike graffiti, they are not permanent, but expected to last 5-10 months depending on the weather.
