London: The Efficiency Magazine, N.d.
8vo, pp. 157, 3pp. advertisements bound in at rear. Original blue boards, lettered in gilt to spine and blind-stamped to front panel. Printed dustwrapper. Text block a little browned, some neat underling in red ink here and there. A very well preserved copy in a near fine dustwrapper but for a little browning to spine, which is very slightly worn at the head.
First edition.
A beautiful copy in dustwrapper -- and, if I sell it, a self-fulfilling prophecy.
