Crookes phosphorescent tube.
                   Crookes flower tube
30 cm in height with a Puluj electrical radiometer on top, early 20th Century. This tube can be found in the Max Kohl catalog nr.100 band III page 1015  on the site of the Max Planck institute, The Virtual Library. 
It was one of the most expensive tubes, made probably by Emil Gundelach.
  The Crookes phosphorescent flower tube or bouquet tube
  is also a beautiful piece of craftsmanship, these tubes were
  made in different sizes. The copper flowers are covered with
  different phosphors, the vanes on top are made of mica and
  turn when the tube is activated forming a moving shadow on
  the flowers below. The stream of electrons demonstrates the
  kinetic effect (which in fact is caused by heat) in form
  of the turning vanes. This shows that electrons travel in straight
  lines which can be seen by watching the phosphors lightning up
  when there is no obstruction in the way of the electrons.
Crookes tube with dancing figure
One of the two similar tubes from the
famous cancelled Christie's 1998 auction.
   A tube with a story
  Here a tube from the famous 1998 Christie's Pressler auction
  which was cancelled due to the fact that the tubes were not
  as "old" as stated. Just before the auction someone noticed
  the yellow M from a well known fastfood restaurant crafted on 
  one of the radiometers.... (see page 12 from the catalogue) 
  The tubes in the catalogue appeared to be recently made by
  some skilled glassblowers with the use of remaining parts
  from the old Pressler factory. The auction was cancelled.
  These tubes are still regularly for sale on auction sites.
  Despite it's young age these tubes are fine pieces of
  craftsmanship and become real collector items.
