Plaster Wall Hanging Busts

Well made but not sure of origin.
From the 50s or 60s I imagine?
They came from the sale of an elderly couple who were downsizing from their 1950's home to a retirement home.
Quite fragile and a bit crumbly when handled.
The one on the right has lost a bit of lower turban.
No maker's markings.
For some reason I keep hearing the 'Lawrence of Arabia' theme song in my head?
