Today’s poster.

A neat typographic effort by the Boulton Paul aircraft company, thirties font in fine form.

But that logo. Certainly it’s a combination of a roundel and the name, but it also looks rather like the very identifiable London Underground roundel logo, still in use, and globally recognised today. Intentional similarity? Some gap to mind.
