Toledo is fortunate enough in having just the murals he did for the cathedral, but there's more to the story.
In 1945, John de Rosen painted an altarpiece and two murals for St. Mary's in Edgerton. I still haven't seen clear pictures from St. Mary's, but everything I have seen makes me suspect my source may have been right in calling it the most beautiful parish church, not just in the diocese, but in Ohio.
These pictures were scanned from an article in the Chronicle. I'll post more of the story tomorrow.
