FOLIO, Felix (John Page). The Hawkers and Street Dealers of the North of England Manufacturing Districts. Manchester: Abel Heywood and London: T.W. Grattan, [1858]. Second edition. Yellow engraved pictorial wrappers. vii, [2], 10-140, [6 pp. advertising]. 8vo. Upper right corner stained, chips at spine (loose), dog-eared pages but text block generally clean and bright. Uncommon. As the title page states, this infrequently encountered text lays bare the swindles of ?quack doctors, cheap johns, needle-dodgers, street ballad sellers? and others of their ilk. But more importantly it discusses a wide range of techniques for conning and hustling, including discussions of holding out and planting dice, pickpocketing techniques (including the installation of a blade in a finger ring), and the doctoring of food.
