The letterpress is the same as the volumes in the Popular Library of Art, but it is reset, the size of the volumes being 8¾ ins. by 5¾ ins. There are no less than 32 plates in each book. Bound in cloth with gold on side, gold lettering on back: gilt top, picture wrapper, 3s. 6d. net a volume, postage 4d. This is the first time that a number of photogravure illustrations have been given in a series published at a popular price. The process having been very costly has been reserved for expensive volumes or restricted to perhaps a frontispiece in the case of books issued at a moderate price. A new departure in the art of printing has recently been made with the machining of photogravures; the wonderfully clear detail and beautifully soft effect of the photogravure reproductions being obtained as effectively as by the old method. It is this great advance in the printing of illustrations which makes it possible to produce this series. The volumes are designed to give as much value as possible, and for the time being are the last word in popular book production. It would be difficult to conceive of more concise, suggestive, and helpful volumes than these. All who read them will be aware of a sensible increase in their knowledge and appreciation of art and the world’s masterpieces. The first six volumes are: RAPHAEL. By Julia Cartwright. BOTTICELLI. By Julia Cartwright. G. F. WATTS. By G. K. Chesterton. LEONARDO DA VINCI. By Georg Gronau. HOLBEIN. By Ford Madox Hueffer. ROSSETTI. By Ford Madox Hueffer. THE CROWN LIBRARY The books included in this series are standard copyright works, issued in similar style at a uniform price, and are eminently suited for the library. They are particularly acceptable as prize volumes for advanced students. Demy 8vo, size 9 in. by 5¾ in. Cloth gilt, gilt top. 5s. net. Postage 5d.
