Exemplary 4.25 x 6.5 cabinet photo of Robert Louis Stevenson in a three-quarter-length pose by W. J. Hawker of Bournemouth, neatly signed on the mount in ink, "Robert Louis Stevenson." In fine condition. Encapsulated in a PSA/DNA authentication holder. Just the fourth signed photograph of Stevenson that we have offered, this marvelous portrait dates to circa 1886, when Stevenson was living in coastal Bournemouth, England, and writing the tale of Jekyll and Hyde. A superlative literary piece.
