Handkerchief Magic by Will Blyth

Handkerchief Magic : How to Entertain and Amuse Children or Adult Audiences with a Pocket Handkerchief
From 1922 comes a very informative book on handkerchief amusements: magic with ordinary handkerchiefs, including a section on false knots, prepared handkerchiefs, and handkerchief effects with apparatus. All well described and illustrated.
