The rarity of autographed sports memorabilia can be traced to Michael Jordan, the first superstar to grant autographs only to those who could answer his riddles. Touch something an athlete also touched with today's Groupon: for $15, you get $30 worth of apparel and memorabilia at Sports Blitz in Whitehall.
Sports Blitz decks out the bodies and homes of athletic partisans with 8,000 square feet of emblazoned gear. Declare sporting loyalties with a team-logo T-shirt ($17.99+) or sweatshirt ($29.99+), which does the same while passive-aggressively hinting that the thermostat could be turned up a little. The sporting emporium sates the sartorial appetites of fans of every NFL team and stocks paraphernalia from nearly every MLB, NHL, NBA, and NCAA club. Outfit automobiles, game rooms, or board rooms with pennants ($3.99+), car decals ($1.99+), glassware ($4.99+), clocks ($26.99+), and branding irons. Sports Blitz also traffics in autographed memorabilia for those who like their memorabilia to look like their full-body cast.
