Obviously, this thread won't be "Bob Freedman Territory."
I have 100's of Giants bumperstickers but these are some of my favorites. "Get 'em Giants" is dated 1961. The Nixon one is 1962. The "Stamp Out Candlestick Park" relates to one man's mission, shortly after the park was opened. His little brochure is pretty funny.
Anyone else got unusual bumperstickers? I wonder when the earliest baseball related ones were made?
