interesting topic; I was just thinking about this today and i decided on
the late 1800's - early 1900's ... somewhere around there Right around the time film was invented...I just love old silent film and films that weren't even films back then (ie, one that was just a girl dancing, another was just a person sneezing) those 2 are the one's that i'm eventually going to be putting in my sig when i get around to it.
