Toledo's Rosary Cathedral was initially designed by architect John T. Comes, and the massive mural in the apse was painted by Felix Leiftuchter. Their work can also be seen at St. Columba in Johnstown, Pennsylvania.
Lieftuchter completed the mural in 1918, and it features imagery of World War I, as well as steel mills and industrialization. St. Columba's is no longer open as a parish, but you can read about plans for re-use HERE. St. Agnes in Cleveland was also a collaboration of Comes and Lieftuchter; see a previous posting HERE.
