Artist Nathaniel Ruleaux leads a community project called “To See If I Could Go Home: A True History Paste-Up” at the Union for Contemporary Art in Omaha on Thursday. His son, Luca, 3, walks away after handing Ruleaux a print to use to demonstrate the project. A member of the Oglala Lakota Nation, Ruleaux often uses his art to bring attention and activism to Native stories.
