Artist Robin Faulkner has created four historical paintings of buildings that have housed the Downers Grove Public Library. The works employ gouache, pencil, and watercolors. Three were commissioned by the Downers Grove Friends of the Library and completed in the 1980s. Owner Services, Inc. donated the fourth for the dedication of the new building in 1999.
