Hmmm... Feeling paranoid?

Brighter now?

Nostalgic?

Excuse me?

Yay!

That's nice, but what's all this got to do with photography?

Londoners have been noticing these strange messages around the Underground recently. They're the latest installment of Platform for Art, which since 2000 has been presenting new artworks to 'enhance and enrich the journeys of millions on the Tube every day'.

(There's a grand histroy of this on the tube, and from 1908, managing director Frank Pick began commissioning leading artists such as Man Ray, Edward McKnight Kauffer and Graham Sutherland to work on innovative poster campaigns.)

The latest commission is Anna Barriball's typographic artwork About 60 miles of beautiful views, featuring enigmatic texts. The reason for featuring them here is that each of the texts is taken from the back of found photographs. Tenuous I know, but we thought we'd share.
