From my late fathers box of things, found this and can ID the Staubach autograph easily enough but the other one not so much.
Roger Staubach on the left; unsure of the autograph on the right
Yeah, sort of like my own sig - I can't decipher that one on right at all.
Edit: Did a search and found another but again no clue on 2nd sig either. https://www.ebay.com/itm/Roger-Staubach-Autographed-Football-Paul-Anderson-Youth-Homes-/163638610052
My pop was great personal friend of Joe Gibbs and can't think of anywhere else he'd get something like this - he was very involved in Gibbs Youth for Tomorrow group. Was reviewing some Gibbs sigs and they seem all different but in the style above...could it be Gibbs? Checked this collectibles site for autograph examples on him: https://www.sportscollectibles.com/joe_gibbs_autographed_signed_1992_pro_line_football_card_131_psa_dna_authentic_c_p7641750.htm
