A few members have mentioned that its a bit difficult so here are some clues. First off I would like to apologise to our older members who sent me glass plate negatives of them in their early days, unfortunately I was unable to scan them. To rule out some choices

28 is not James Dean

30 is not a member of the Royal family

14 is not Miss Elisabeth Bennet

8 is not Normie Rowe

26 may or may not have been nominated for an Oscar

15 is not a well known actor

22 is not Cliff Richards and the Shadows but the time period is close
