Smallest shop in london

In recent years two types of ad-hoc shops have sprung up in London. One is the booth selling mobile phones, sims, etc.

The other is the fruit and veg stall selling in 1-pound bowls outside of shops http://www.urban75.net/forums/threads/veg-fruit-from-market-stalls-%C2%A31-bowl-sellers.183082/  (sorry no photo)

But both would be hard-put to rival this East End shoe seller from 1900
