Hair today

On one of those days where walking almost anywhere in central London makes you think the collective noun for tourists is "a drift", circumstances enforce attention to local detail.

Such as this particular poster, in the little bit of Soho now branded as Chinatown. With bunting of the flag of what used to called Red China fluttering overhead, I suppose the name is explicable.

But in among the photos of hairstyle models, there's no picture of the man himself. I wonder why?

Karl Marx - hairstyle model. Or maybe not.

What's the date, again?
