This is an authenticated Mark McGwire autographed baseball. The baseball comes in a protective case and has a Certificate of Authenticity. This a perfect gift for your diehard Cardinals fan since not only has McGwire been a fan favorite in the past but was also the Cards Hitting Coach in 2012. I will also include the 2 McGwire baseball cards pictured. If interested, please call or text (! Cash or Paypal are the only forms of payment I will accept.
