What Lies Beneath?

Some renovation in Skipton reveals old advertising. I remember my Grandfather always smoking the cigarettes with the sailor on the front of the packet.
Anyone know what "Quality Keynote" (to the right of the Capstan sign) refers to?

Extra: Shows the full building. Some research on the internet found this picture from The Rowley Collection which consists of over 600 photos of old Skipton. Fantastic Resource!
