I found a truly rare piece of Celtics memorabilia on Ebay today. Ebay seller swoosh26.2 has a signed deadstock pair of Dave Cowens Nike Blazers. The shoes are also signed by the Celtics legend. Cowens was one of the first NBA stars to embrace Nike. It is very rare for sneakers of this age to come in the original (OG) box. Making the shoes even cooler is the shipping label that reads “Organization Boston Celtics”. The shoes are listed for a cool $2,200. High prices, but the seller is accepting offers. CLICK HERE to bid.
