Just in case you have some extra money laying around and want a souvenir from the Rasheed Wallace signing. From the auction page on Celtics.com:
The Boston Celtics are poised to make another run for Banner 18 this season after the key off-season pickup of Rasheed Wallace! To celebrate the signing, the Boston Celtics Shamrock Foundation will be auctioning off an Autographed Authentic Rasheed Wallace Home Jersey. This is the first official jersey Rasheed was issued and wore as a Celtic.
The proceeds from the sale of this auction will benefit the Boston Celtics Shamrock Foundation, the Boston-based charity committed to providing healthcare, shelter, and vital services for children in need.
