Advertisement on Routemasters

[kris]

Hello! 

Still working on finalising my short spy film set on a Routemaster in 1957. One of the final things we have been working on are faux ads in a 1957 design aesthetic.  As you can imagine we’ve done quite a lot of research and visited the LTM Library and our shooting bus location.

One thing that I have found nothing on is the corner frame with rounded corners on the wide seat just below the stairs. 
(the one visible in this photo timebus.co.uk/graphics/vehs/oplat/327-0028-downstairs.jpg ) 

Would that frame also have contained an advertisement, but just folded in halfs? Or would it contain something different like timetables etc?

Any pointers or information would be very welcome! 

Thanks!

Sorry, but one of the principles of our late founder was that we don't cover the London Bus network, or buses in general. There are several other forums who will be much better placed to answer your question.
