The three flyers reproduced here were handed to me by one of the messengers. Disaster Amnesiac actually attend the bar-b-q that is advertised!
I am not sure if they ever got their union up and running. It seems as if there are a lot less messengers wheeling their way around downtown S.F. these days. I guess the advent of advanced digital reproduction and communication rendered many of their services moot? That said, I still see a few flying past on their cool bikes; there is one guy that's been at it so long, he reminds me of Moses or something! And, hey, the bike messengers were given that ultimate cyberpunk imprimatur, seeing as that a messenger was the main protagonist of a William Gibson novel.
Anyway, a small piece of S.F. Labor History, preserved and presented here.
