My Favourite Road Sign.

Is having a favourite road sign odd?
Between '57-'67 Jock Kinneir & Margaret Calvert undertook one of the most ambitious information design projects ever, in order to bring coherent, easily legible & uniform signage to our roads. They succeeded brilliantly!
As an old bike enthusiast I love that their motorcyclist, like most of their designs, is still in use today. The open-face helmet & Avon style fairing are clearly of the "classic" era.
Calvert also has a font named after her, maybe Neville can tell us more about that?
