6Burgh's Bio:  I've been collecting in-person autographs since the early 1980's.  Retired from the United States Air Force (SMSgt/E-8) after a 21 year career that includes four contingency deployments to Afghanistan and Iraq in support of the Global War on Terrorism.  I obtain all signatures in-person, directly from the athlete/celebrity/musician at stadiums, hotels, training camps, and public appearances.  This is how I can assure you all of my items are 100% authentic.  Any item you purchase from me can be identified with the EXACT location and date of when it was signed.  If desired, I will reveal the location/date to the buyer after payment is received.
