1967 to 1974 Game used equipment wanted

[sfgiantsfan44]

Hi! I collect any game used pro or college baseball, football, or basketball equipment from about 1967 to 1974. This includes jerseys, pants, warm-ups, jackets, etc. These were the years that I really followed sports as a kid.
What have you? What do you collect?
I will buy or trade.
Thanks, Andy Sandler alwysyakn@aol.com
