Help with rare vintage Iowa Hawkeyes NFL cards
 

Lots of experts on this board. I have a buddy who is working on a complete run of Iowa Hawkeyes Rookie NFL cards. He needs the following cards. Any help would be appreciated
1933 diamond matchbooks Joe Laws
1956 Parkhurst Cal Jones
1952 Bowman Hubert Johnson or Johnston
1948 Colts Matchbooks Sam Vacanti
Please pm me if you have any of these.
Much appreciated
Eric
