Do these 1970's football jerseys look to be authentic? (Bradshaw and Staubach)

[apujols04]

Here are the pics I promised. Any input on these items would be greatly appreciated.















Please let me know what you experts think about these 2 jerseys. I guess the Unitas jersey is no good. What are the value of these if they were/are store models. Either way they are vintage and nice to look at.
