The wall outside RoCA on Court Avenue has a new look.   Iowa City artist duo Thomas Agran and Drew Etienne completed a massive, three-story mural that will cover the upper part of the wall, replacing a collage of post cards.    Liz Lidgett, who runs Liz Lidgett Gallery and Design, curated the wall’s original murals almost 10 years ago with the idea that it would be a temporary “quilt” of artworks that would be redone periodically. The wall was completed over the course of three years, layer by layer.   🎥: @nixsonbenitez 📰: Addison Lathers   #Iowa #Art #DesMoinesArt #DSMUSA #DowntownDesMoines #DowntownDSM
