Robert Sayer, (1725-1794), The Artist's Vade Mecum; being the whole Art of Drawing, taught in a new work, elegantly engraved on one hundred folio copper plates; containing great variety of examples in every branch of that noble art; as parts of the face, heads, hands, feet, academy, antiques, and groups of figures, beasts, birds, insects, flowers, fruit, shells, ornaments, buildings, landscapes. Collected from the works of the greatest masters. To which is prefixed, an Essay on Drawing: with introductory rules for the use of learners: in which the first principles of that useful and noble art are explained in such manner that it may be attained in a short time without a master. 1762; 8pp., 100 numbered copper plates [lacks #46]. Light foxing and browning to the paper throughout, several ink markings, mainly to the title page; Contemporary boards but lacks spine; pages mainly in bundles. Contemporary ownership name of Mary Hanbury, June 1738. 4to.;, [Printed and published according to Act of Parliament: and sold by R. Sayer, at the Golden-Buck, in Fleet-Street. Mdcclxii]. Despite its authoritative title, this is not so much a detailed drawing manual as a rare and fascinating cross section of the stock of the print seller and publisher Robert Sayer in 1762. The Vade Mecum was first published in 1762, of which just 6 copies - British Library, Getty, Yale Center, DeWint, State Library of Australia, one sold in London in 2015, and this example are recorded. The second edition is recorded in just two copies (Yale, and University of California). A third edition appeared in 1776 (Bl, Leeds, Columbia, Yale Center only).
