Halloween hauntings: William Hope's spirit photographs

A photograph of a group gathered at a seance. The information accompanying the spirit album states that the table is levitating – in reality the image of a ghostly arm has been superimposed over the table stand through double exposure Photograph: William Hope/Getty Images Photograph: Getty Images Two faces appear around a man and two women – one, an elderly person, and the other that of a younger woman shrouded in a cloak Photograph: William Hope/Getty Images Two of Hope's friends are seen with a figure – the couple's deceased son – at the wheel. Hope had suggested a photo opportunity for the 'chance' of obtaining a spirit impression Photograph: William Hope/Getty Images A young woman's face appears as if floating above the sitters, draped in a cloak. Hope may have already held her photograph in his studio, or he may have asked the couple to supply photographs of deceased relatives under the pretence of using the image to contact the spirit world Photograph: William Hope/Getty Images Two faces – that of a man and a girl – appear, surrounded in 'mist', above the group. Hope founded the spiritualist society known as the Crewe Circle and his work surged in popularity after the first world war, when many bereaved people were desperate to find evidence of loved ones living beyond the grave Photograph: William Hope/Getty Images Photograph: Getty Images A man's blurred face appears next to the sitter, surrounded in an ethereal-looking 'mist'. The signature in the upper right hand corner belongs to the sitter Photograph: William Hope/Getty Images A male face appears on its side above the sitter's head Photograph: William Hope/Getty Images A photograph of Welsh mediums and brothers Joe and Will Thomas. The Thomas family claimed that the image superimposed over the sitters was the only photograph of their deceased grandmother in existence. Hope, however, would have used an existing photograph of a woman to create the illusion Photograph: William Hope/Getty Images Photograph: Getty Images A woman mourns for her husband in a Chapel of Rest, standing by his body which is wrapped in sheets and laden with flowers. The woman's son stands beside her. The image of a man's face has been superimposed over the original photograph. The spirit album notes that the family were Roman Catholics and believed in life after death Photograph: William Hope/Getty Images Photograph: Getty Images The face of a younger woman appears between the men, surrounded in an ethereal-looking 'mist' Photograph: William Hope/Getty Images The face of a young woman appears over the woman on the right. The reverse of the photograph reads: 'Why is the child always pushing to the front?' and 'Do we get messages from the higher spirits?' – perhaps questions the women wanted answering. One of the sitters, at Hope's request, has signed the plate for authentication Photograph: William Hope/Getty Images A man's face appears in a haze of drapery on the right of the photograph. Thomas, a medium from Wales, did not recognise the superimposed image. Thomas has signed the bottom of the photograph, 'Sincerely Yours Will Thomas' – perhaps this indicates a friendship with Hope Photograph: William Hope/Getty Images A woman's face – draped in a transparent cloak – appears over the group Photograph: William Hope/Getty Images Photograph: Getty Images
