I love stained glass, which I've usually sought out in churches. In this case, I found a huge selection, very nicely displayed, at the Stained Glass Museum on Navy Pier in Chicago. Several of my favourites were Tiffany, but I'm not sure which are which because I didn't take notes as I was walking through taking photos. Not sure if this is one of them: the style is similar, but the use of triangles would be very unusual.
