Andy's First Grand Slam

It has been a long time coming but now that one has been achieved Andy Murray will surely go on to win more grand slam titles. In Dunblane today there were a few congratulatory notices and so on but this shop window display caught my eye. Notice the typewriter which the lady who set up the display reckoned would have been in use 76 years ago when Fred Perry won the US title and also the Big Apple.
The shop window is in fact that of Andy Murray's grandfather's opticians business.
