The 'Hints and Hobbies' series amused and enlightened 1920s British cinemagoers with all kinds of invaluable advice which, we can only hope, few actually tried at home.

They included a guide to cleaning your mink stole with the aid of bran; tips on how to put on a pair of new kid gloves without splitting them and, for the energetic, an alarmingly vigorous work-out for the pectoral muscles.

Best of all are the 'Hints to the Ladies on Jiu-Jitsu' - seen here - which feel unnervingly like a long lost chapter from the history of lesbian erotica. (Robin Baker)
