The Sign of Four
George Newnes, Ltd.
Souvenir Edition, in dust jacket
The gray-green jacket included ads for Newnes’s Thin Paper Series on the front jacket flap and the Caxton Series on the back jacket flap. The back cover advertised the four volumes in the Souvenir Edition. Readers could buy each volume separately for 3/6 or as a set, with top- edge gilt, in a slipcase for 14/–. (In 1901, a month’s rent was 10/– for a London professional man.)
