Llanidloes carnival?

davidpoolelllanicarnvial“This Photo of a Llani carnival is from the early 1950’s ( I think) , do you recognise anyone? I found it in my mothers old collection of photo’s from when we lived near Llanidloes”. Posted by David Poole on another FB page. The setting has now been identified as Vaenor Park, Llanidloes. Anyone know the people?

Interestingly Vaenor Park is currently for sale.
