Its a lame blurb, the story of the Doves Typeface is here: http://www.economist.com/news/christmas-specials/21591793-le... which is somewhat interesting. That they have found a few more pieces of it is, interesting as well. No need to click the link though and read this :

Printing blocks for a typeface called Doves Type have been discovered in the River Thames.

The font has not been used for nearly a century as the printing type blocks, used to print letters, were thrown into the river in 1917.

And have your screen start talking to you with an advertisement.
