Original protest poster, Strong and Stable My Arse, by Jeremy Deller, published by flyingleaps (2017). Signed and dated on the reverse, from an edition of 300.

Established in 2016, the flyingleaps project works with established and emerging artists to “introduce fresh voices into the ‘visual conversations’ that echo round our cities”. This is achieved by exhibiting artists’ work on street poster sites to make “unexpected and thought-provoking contributions to the urban spectacle”.

Over the years we (at C20th Posters) have been delighted to spot these typically temporary displays in London and elsewhere and have collected several examples as a record of the urban poster landscape in the 21st Century. All the examples offered for sale via C20th Posters have been supplied directly by flyingleaps.

This poster is the most famous produced by the project, even appearing on the BBC news. Deller adapted (and undermined) the oft repeated phrase of then Prime Minister Theresa May that she was providing Strong and Stable government, by adding My Arse. This addition was reminiscent of the cynical pronouncements made by the Ricky Tomlinson character Jim Royle in the popular sitcom The Royle Family, and certainly chimed with the popular mood at the time, going through 3 print editions to satisfy demand.
