On Saturday, January 24th, 2009, NPR had this short segment with organist Jim Riggs about the Art Deco movie palaces and the Wurlitzer Organs. LINK
Photo is from my personal collection of the Elsinore Theater in Salem, Oregon. Here is a link to a mini-tour of the theater taken several years ago.
UPDATE: To continue the Wurlitzer Organ theme, here are some delightful videos from YouTube:
