This picture brings back memories. I wonder how long that entrance to Piccadilly tube station has been in use. I am sure it was already old when I first saw it in 1957.
The other thing that I notice is the advert for Hugo Boss. To be advertised in Piccadilly Circus, this German clothier with a checkered history has certainly worked hard to achieve the recognition that it would not have had during the early years of this staircase.
