The Hemingray plant does appear in artwork. This mural appears on the floodwall along the Ohio River on the Covington, KY shoreline. At my urging, artist Robert Dafford included the Flint House of the Hemingray factory in one of the murals he painted this summer. Although not prominent, it is there. It's the building with the twin smokestacks above the arrow. Thanks to Darin Cochran for snapping the picture.
