This month, photographs of some of these sites have appeared on billboards and bus shelters in Hull, part of the photo project Absence of Evidence, led by the artist duo Henry/Bragg, working with a group of former street sex workers from Hull called An Untold Story: Voices. “One is the view from the corner I worked, another is the doorway I stood in when it was raining,” says Amanda Hailes. “All the photographs represent something we have experienced, lived through and survived.”
