Just arrived, a mint condition East Surrey Regiment cap badge, slider marked to "J.R. GAUNT LONDON" mounted on a folding foolscap sized advertising card of the British Aluminium Company.
Presumably the advertising card was distributed with other unit badges which were perhaps produced by different manufacturers.
The first time I've seen one of these cards.

Edit: I typed "beret" badge - the badge is cap badge sized, it's not the beret badge.
