Help.....I have a photo of the exterior of this church ..from a book.....and have misplaced/lost my interior slide....Schreiter's work, all blue with some white, the church is right on the river in... Koblenz?? Anyway, I have looked thru several books on German glass, but no luck....does anyone have an interior photo they could scan and send me? This is for a 60 minute presentation and I am trying to add additional photos from my usual 40 minute talk. (perhaps someone who was on the Dick Millard/Karen Hendrix trip from about 20 years ago?) Thanks much!!
