This protest message from Led By Donkeys was ploughed into a field at Manor Farm, Wiltshire, UK. Via Eye magazine, who comments: “That’s what I call big type.”

It’s big indeed: At a cap height of 40 meters (that’s almost 113,386 PostScript points), it’s said to be the largest-ever Brexit protest message. Technically, this is not type, of course, but lettering, built up from several “strokes” made with the rather unusual tool of a plough. I’ll go out on a limb and claim this piece still qualifies for Fonts In Use. To me, it looks like a clear case of lettering derived from a typeface. The typeface that the letterforms were modeled after what appears to be Century Gothic Bold. See the comments for details.

The text card shown towards the end of the clip is set in K-Type’s Keep Calm. This font family is based on the lettering that was used for the now famous World War 2 poster originally designed in 1939.
