Dunlop Tennis Tournaments in the 50's

In the 1950’s and 60’s Dunlop used to sponsor a series of tournaments all round the country at places like Southport, Torquay, Frinton etc.

Does anybody have any information on these tournaments? Or any of the posters and handbills?

The reason is that as a child, I used to work weekends and during the holidays at my father’s printing firm in Wood Green. He used to print the handbills used to publicise the tournaments. And I used to set the type!

I would love a copy of one, if any still exist!
