I don't have any signed momentos. (Had a signed copy of Bill Walton's book, which was regifted to another friend.) I have a warm up suit, pictures, signs and books. But my two favorite momentos are a Celtics Key Chain which was Christmas gift 7 years ago from my husband that I still use, and a pair of Celtics slippers sent to me by Master Po, that I wear every game while I chat in the CelticsBlog chat room. I cherish them both.
