What are some good sites for old and unusual art glass? I am looking for information about two specific pieces - one is a jack-in-the-pulpit vase, about 16 inches high and blue-green, possibly Tiffany or Stuben. The other is a lamp, with a glass base and top, probably layered, acid etched with large brown scarabs, dark apricot in color and about 12 inches high. The lamp has a 1/2', small diameter glass rod embedded in the base that looks like a barber's pole.
