After much research, I have discovered that a couple of posters and a set of other drawings I have are by Kathleen Stenning. She is more known for some of the iconic London Underground posters in the 1920s.
In the main set of drawings, the group of friends were called the Launderers - they were authors, artists, actors and who were active in London between 1924-1934.
The names - Brian Hill, Antonia White (Tony), Colin Gill, Joan Garstin and Alick Schepeler are to name a few.
I was wondering would these be worth anything?

Thank you
