Help with the worth of what I have.

People I am new to this site and new to memorabilia selling and buying, If anyone can help me or maybe let me know that they think I would appreciate it. I bought something at a yard sale recently from here in a small town in Oklahoma. The man who's stuff it was lived here and played for the Philadelphia Eagles in the late 1940's and was on their two World Championship teams. In this album there are several things but the one that I think is most relevant is a program from the 1948 Eagles vs Boston Yanks and on the front the whole team has autographed it in ink pen signatures. I do know that there are 3 on there that are in the Pro Football Hall of Fame, they are: Steve Van Buren, Pete Pihos, and Alex Wojciechowicz. There is also in there a team photo with coaches and players, also some individual photos with some of them autographed. There is even the menu of their Championship Dinner they had and where it was held. Just don't know much about this stuff but I know that it could be worth some money. Thanks for any help anyone can give me.
