"A man, boy and makeshift ghost by a tombstone. Hand-coloured magic lantern slide, 19th century. This slipping slide consists of one glass slide which is moved across another, fixed slide, which is painted with two phases of a simple movement. Black patches on the slipping slide alternately cover and uncover the two phases of movement. One of a pair with CIN/C000058."
