Fifth edition. 12mo. xxviii, 211, [1, publisher's advertisements] pp., folding letterpress table at rear, woodcut head and tail pieces throughout. Contemporary quarter calf with marbled paper covered boards, spine with five raised bands outlined in blind, manuscript paper label to second panel (neat book label of 'John Tutin' to front pastedown, a few manuscript annotations to the table of contents on pp. xxv-vii in an early hand, just a hint of occasional faint spotting, contents otherwise generally clean; light surface wear to boards, corners gently bumped, notwithstanding an excellent copy). London, S. Hooper. The fifth edition, expanded from the exceedingly rare first edition of 1761, of what is generally considered the first guide to the stock exchange, based on the author's own experience of losing 'a genteel fortune' in 1756. Thomas Mortimer (1730-1810) was one of the earliest experts on the operation of the stock exchange established in the coffee-house of London's Change Alley. Every Man his Own Broker is a practical guide for would-be speculators, warning about the dangers of getting involved with brokers and offering insight into the financial world of mid-eighteenth century London. Mortimer was the first to write about the terms 'bear' and 'bull' markets. The book proved popular, with fourteen editions published within forty years.
