Last summer, Minor League Baseball (MiLB) sent the biggest baseball that could legally travel the highways on a road trip to 15 ballparks across the country. All to unite Minor League clubs and their incredible communities around a common cause: setting a Guinness World Record. The "World's Most Autographed Baseball" experience was beautifully simple—sign the ball, take photos, share on social—but the emotional impact was profound. Every autograph made fans part of baseball history. The ball was an 8-foot, 1200-pound spectacle that drew fans before and after games. A branded truck and acrylic transport case turned the ball into a captivating piece of mobile OOH, creating anticipation throughout its 2,600-mile journey from town to town. Each of the 15 stops became a unique event within the larger activation, with local fans adding their hometown flavor to this national record attempt. The tour culminated at MLB headquarters in NYC, where Commissioner Manfred added the final signature. Afterward, a Guinness official certified the record. With 6,750 signatures collected, the campaign proved that the most powerful activations don't just entertain—they invite participation in something bigger, celebrating the authentic charm that makes Minor League Baseball truly special.
