Roughly 6 x 5 1/2 inch autograph book page.
I have shown part of the next page , so as you can see the full title of the play.

The autograph book belonged to a lady who lived in Nottingham and she was given the book in 1950.
I think all the pages were signed in London, Brighton and Bournemouth.
Most of the signatures are dated and the first one is from 1949 and the last 1956.
A lot of the pages have multiple signatures.
