No- I don't have the hard copy letter. But I pulled the authentication verification from PSA's website. You can see from the Bat Rack streaks (and other markings), that it's the same exact bat. You can zoom on the picture that PSAprovides. Please click the link below...

This Bat is actually from the 1980 - 82 time frame. Please contact me with any further questions, and thanks for your interest!
