No new observations, but...
..pretty good value for this type of lamp. Nice heavy base, pretty glasswork. I was a bit disappointed that the butterly isn't pieced together from glass, but rather, is a metal overlay onto the glass beneath. And yes, it is blue. However, when lit, it's very pretty and much lighter colors than many of these Tiffany lamps- actually provides functional, bright light if you intend to use it as a desk lamp. It's not art gallery workmanship, but about what I expected.
