I am looking for a poster of Larry Bird diving for a loose ball, with
his quote, "It makes me sick when I see a guy just watching it go out
of bounds." I have checked ebay and various poster websites. I need to
buy it right now. Used is fine.

This Poster I believe came out of a Sports Illustrated Magazine. It
was actually an add for Converse.
I just happened to pull this out and save it when I was a kid. It is
now framed and hanging in my office as a reminder of the importance of
never giving up. As far as selling it the price may not be cheap.
