The church where my brother-in-law is the music director (St. Michael's Church in NYC) has a huge collection of Tiffany Glass windowns and mosaics.
These are Louise Comfort Tiffany, not his studio.
These really deserve to be seen in their original size (the photos as well as the windows) in order to really appreciate Tiffany's amazing work with color.
Next time I'm there I'll shoot more!
