London Underground & the Boat Race

I was confused when this arrived the other day.  In order to explain my confusion, I'm going to quote the entire information blurb from the back of the card. 

Underground

Boat Race

Charles Pine, 1923
Copyright Transport for London

Charles Paine was a versatile and prolific designer.  His time at the Royal College of Art was interrupted by military service.  After graduating Paine left London to work for the Art Department of Edinburgh College of Art.  He then went on to work in Glasgow, designing stained glass for Guthrie and Wells.  During the 1920s he designed textiles and posters for a wide range of clients.  In the 1930s he lived and worked in Welwyn Garden City, before moving to Jersey.

The only problem is that I still couldn't see the connection between London Underground and the Boat Race.  However I've now done some ferreting around and I find that London Underground produced posters to encourage people to travel to the Boat Race by tube and they did this from 1910 right up until 1990. 

In an effort to encourage people to use the tube outside peak hours, they advertised all sorts of sporting events, but the posters for the Boat Race (according to the Boat Race people) were the most visually stunning.

I've now spent a happy half hour browsing the London Transport Museum's online shop.  do you know you can now buy armchairs and sofas covered in the new Routemaster moquette?  The designs are the same as those used on London’s transport vehicles.  The latest must-have, apparently.
