Illustrated cover of sheet music for a music hall turn performed by Dan Leno; words by James Newland, music by George le Brun. The song was inspired by Stirn's Detective or Concealed Vest Camera of 1886 which was worn under a garment, with the lens protruding through a button-hole. As the song sheet shows, the detective camera could be used for a variety of purposes - from covertly photographing public disturbances, to capturing burglars or unfaithful spouses on film. Dan Leno was the stage name of the English comedian George Galvin (1860-1904), who began his career at the age of four singing and dancing in pubs and became a regular performer at the Drury Lane annual pantomime.
