Harrison and Co designed this year's Brighton Festival look and feel. After hearing about the themes of the Festival they created an lead image that uses Victor Skrebneski's iconic photograph of Vanessa Redgrave from the 60s, the scene from Sandro Botticelli's Birth of Venus and Milton Glaser's Bob Dylan poster as points of inspiration.

The poster uses the typeface Progress, which appears to be modified to reference Rennie Mackintosh, leading Gareth Hague, designer of the typeface, to remark on Twitter:

Oddest use of Progress.

An unaltered Progress is used throughout the branding, including the website.
