A 1970 Jackson 5 concert poster from their huge debut year. Michael Jackson was not even a teenager yet for this Jacksonville, FL show, advertised by a large Day-Glo Globe concert poster that harkens back to the poster styles of the 1950s and 60s. Enthusiastically discussed by collector Pete Howard of PosterCentral.com (phone 805-540-0020, email pete@postercentral.com).
