August 13th, 1967 Boston Patriots Pre Season Program versus the Baltimore Colts. The game was played at Harvard Stadium. 

The program besides it being rare includes 2 pages of Signatures inside that have been authenticated by PSA/DNA. 12 total signatures. PSA has identified 10 of the 12 and 2 they could not determine. The program is in nice shape with a tight spine with the cover having some wear but no rips or tears. Here are the signatures: 

Jim Nance: The only Boston Patriot in the group. D: 1992
Bobby Boyd D: 2017 
Jimmy Orr
Fred Miller
Andy Stynchula D:1985
Dennis Gaubatz
Don Shula: HOF D: 2020
Johnny Unitas: HOF  D: 2002
John Mackey: HOF D: 2011
Jim Parker: HOF D: 2005 

Close Ups photos of all HOF players provided. 

2 Not identified: One not indentified is on the page with the players pics. It could be Lenny Moore as it is close to his pic but PSA could not identify the Signature, concisely. 
The other not identified is tough. Just not sure. I took a close up if that one and it is the last pic in the listing. 

These signatures almost 100% were obtained that day in 1967 when The Colts came to Harvard Stadium in Cambridge, MA. 

There is also a story on the return of the Redskins who played in Boston earlier and a neat ticket order form for the upcoming Redskins game. 

Great Program and signatures from when the Colts ruled the NFL and the Patriots were just trying to stay afloat in the AFL. 

Thanks for looking
