What do you collect, and how big is your collection?

[Jack Daw at Work]

Watches, both pocket and wrist.  My latest prize find that I don't mind wearing is a 1935 Hamilton, porcelain-face railroad watch.  Because of their expense and difficulty in finding, my collection is not extensive.

Lava lamps, I have somewhere between 125 and 150 of them from a nightlight sized up to my Colossus El Macho (pictures on request)
