Have a signed basketball you’d like to display? An autographed basketball jersey? Call Ed Evans at the Sports Cooperative. Evans only opens the shop by appointment — don’t drop in — but he answers the phone or returns calls promptly. Ed specializes in framing sports memorabilia, so he treats it right: No baseballs nailed to their mounts. No torn jerseys. No value-destroying glue spots. In fact, the other two members of the Sports Cooperative sell memorabilia, so if you’re looking for a gift for a sports lover, this Concord store is a one-stop shop.
