Good afternoon! I recently came upon the recent opportunity to purchase a multi-autograph signed copy of Parachute Infantry by Webster. The version is the Easton Press leather edition. The seller has no certificate of authenticity...but the signatures appear realistic from the pictures. I was wondering if anyone has ever come across or owns a signed copy of the above book, and has any information at where and when they were signed. Thank you so much in advance!
