Great Pipe Organ in the Historic Boardwalk Hall
Since I stumbled across the oldest organ and musical instrument in the world, I thought I would take a picture or two and share it with you. 
I also found a pamphlet with some information and more pictures as you see below.
This particular pipe organ at Boardwalk Hall is by far not the oldest one, but the world's largest one (in terms of pipe ranks). The second largest -- but largest playable one is the Wanamaker organ at Macy's, Philadelphia.
