When we first received our Cathedral Stained Glass, I checked out books from the library to discover the particulars of it. Now, I've forgotten what I learned. I do remember that it is painted glass and is probably European and I'm guessing the time is 1700's or 1800's. At any rate, we have loved it and thrilled that it has an 'S' in the middle of it and it hangs over our front entrance window at the stair landing. I'll add the reason Ken is practicing on his camera is we will be taking photos of real European cathedrals next month.
