Robert Sayer
Robert Sayer was a leading publisher and seller of prints, maps, and maritime charts in Georgian Britain. He was based near the Golden Buck on 53 Fleet Street in London.
Printing Business
Sayer's brother James married the widowed Mary Overton, daughter-in-law of John Overton the print seller. Sayer became her assistant, being called manager of the Golden Buck by 1748, and in this way gradually took over the existing Overton business as a going concern.John Bennett, who began as a servant to Sayer in 1760, and later an apprentice and a free journeyman, eventually partnered with Sayer with one-third share in the Fleet Street business. The business traded as Sayer & Bennett. In 1781, Bennett was admitted to Dr Thomas Monro's Brook House asylum in Clapton. Sayer would seek to dissolve the partnership in 1785 based on Bennett's mental condition. Bennett later died in 1787. Upon the partnership dissolution, the business was renamed Sayer & Co. or Robert Sayer & Co., probably a reference to his assistants Robert Laurie and James Whittle.
Sayer published atlases and other cartographic works, publishing the Mundane System of Samuel Dunn and the famous North American Pilot, which included important charts made by the great circumnavigator and explorer Captain James Cook.
Sayer also had an "almost complete set of copies" of painter William Hograth's plates and sold prints at prices that undercut those of Hogarth's widow and printseller, Jane Hogarth.
Harlequinades and turn-up books
Around 1765, Robert Sayer began experimenting with a novelty format for the juvenile book market, an early forerunner to interactive movable books, according to book historian Peter Haining. The outcome was the creation of the “metamorphoses” format, “a thin book of four sections each with two flaps which folded over, and on each section an interchangeable picture. Beneath those pictures appeared some descriptive lines of verse, and as the reader turned up the flaps in the correct order in the text difference scenes were revealed.”Originally called “metamorphosis”, Sayer would create books featuring the “Harlequins” from popular theater pantomimes. The black and white publications, which were also called Harlequinades or turn-up books, sold for sixpence and the hand-colored ones for one shilling.
Sayer published at least fifteen such titles between 1766 and 1772. Theater historian George Speaight noted that Sayers published at least sixteen titles.
Titles Sayer printed and published include Harlequin Cherokee; or, The Indian Chiefs in London, published in 1772. Academic Dr. Jacqueline Reid-Walsh has located eleven of Sayer's "harlequinades" in the rare book collections of Cambridge University Library, Cambridge, the Cotsen Children's Library, the Lilly Library in Bloomington, Indiana, the Opie Collection in the Bodleian Library, Oxford, the Osborne Collection in the Toronto Public Library, and the University of California, Los Angeles.
By late 1770, Sayer had published four turn-up or metamorphosis books, which became a "craze with children." Rival booksellers, such as Thomas Hughes and George Martin soon copied the "turn-up" format. In the United States, Joseph Rakestraw published "Metamorphosis; or, a Transformation of Pictures, with Poetical Explanations, for the Amusement of Young Persons," by Benjamin Sands.
