Naturally the artistic quality of a book-plate influences its value; the more elaborate designs are preferred to the plain armorials or the printed labels. Pictorial plates, introducing bits of landscape, interiors of libraries, or allegorical subjects, are sought for, as are plates which are accepted as particularly good types of the different styles. In addition to these technical reasons for valuing one plate more highly than another may be given others which will appear more reasonable perhaps to the general reader. All articles belonging to the noted men of the past have a certain antiquarian value greater than attaches to the kindred belongings of their contemporaries of lesser or no fame. So with book-plates. A glance at the list will show a goodly number of names which we remember with pride and interest; the names of patriots, orators, lawyers, statesmen, officers of the army, officers of the state and nation, members of Congress, signers of the Declaration, governors, old-time merchants, authors, divines, physicians, and not a few of that plucky number who stood by the King in trying times--the American Loyalists. Quakers, too, as well as royal office-holders, and titled Americans are among those whose book-plates have come down to us. Of our early Presidents, the plates of George Washington, John Adams, John Quincy Adams, and John Tyler are known to us. All of these except the last, which is a plain printed label, are armorial. Members of the Boston Tea Party, of the Constitutional Convention, and of the early Assemblies are among those whose plates we know. [Illustration: John Quincy Adams.] Of royal officers we have: Craven, one of the Lords Proprietors of South Carolina; Elliston, Collector of His Majesty’s Customs at New York; Sir William Keith, Governor of Pennsylvania; John Tabor Kempe, Attorney-General under the Crown at New York; and William Penn, Proprietor and Governor of the colony which bore his name. Owners of large estates, employers of numbers of slaves, merchants whose vessels carried on a trade with remote and prosperous shores, and who established names that have endured, used book-plates which are still known to us. Among these are the plates from the following families, well-known in New England: Ames, Bowdoin, Cabot, Chandler, Chauncey, Coffin, Lodge, Lowell, Minot, Quincy, Sears, Winthrop, Barrell, Greene, Perkins, Swan, Vassall, and Vaughan. [Illustration: Josiah Quincy] Of those well-known in and about New York may be mentioned, Clinton, Colden, Constable, Cutting, De Peyster, Duer, Ellery, Goelet, Hoffman, Ogden, Paulding, Phillipse, Pintard, Van Cortlandt, and Van Rensselaer. To these should be added the Livingstons, which family had the largest number of book-plates of any we know.
