Original protest poster, Prisoner of More, by Benjamin Irritant, published by flyingleaps (2021). Signed and dated on the reverse.

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.

In our opinion, this is possibly the best poster produced by the poster. I can clearly remember encountering a wall of Prisoner of More posters under a railway bridge at East Finchley station and thinking ‘Wow, who has done these and how do I acquire a copy!’.
