Jnternational Studio Summer Supplement

Uniform with “Corot AND Millet,” - Masters of English
Landscape Painting,” “The Genius of J. M. W. Turner, R.A.”, etc.

THE ROYAL ACADEMY FROM REYNOLDS TO MILLAIS THE RECORD OF A CENTURY

IN spite of the large amount of interesting and beautiful material available for the purpose, no serious attempt has hitherto been made to compile an adequate illustrated record of the Royal Academy. THE SPECIAL SUMMER NUMBER OF "THE INTERNATIONAL STUDIO" will be devoted to the consideration of the work of Academicians and Associates from the year 1768 down to 1868. It will be divided into four main chapters, dealing respectively with the Painters, the Sculptors, the Engravers, and the Architects, with the addition of an introductory historical survey of the Academy as an Institution. THE very large number of illustrations, consisting of PhotograVURES, Colour Plates, and other reproductions, will include, among others, characteristic examples of the work of the following artists:PAINTERS: Sir Joshua Reynolds, Francis Cotes, Benjamin West, Angelica Kauffman, Gainsborough, Sir T. Lawrence, J. M. W. Turner, Sir David Wilkie, Sir H. Raeburn, John Constable, Sir C. L. Eastlake, George Dance, Sir Edwin Landseer, Sir J. E. Millais, etc. SCULPTORS AND ENGRAVERS: Joseph Nollekens, John Flaxman, F. Bartolozzi, Valentine Green, William Ward, Samuel Cousins, Joseph Wilton, etc. A NUMBER of portraits of artists, and facsimile reproductions of autograph letters, will form an additional interesting feature of the publication. THE great expense involved in the production of the Special Summer Number renders it impossible to reprint, and orders should therefore be sent in without delay. “THE GENIUS OF J. M. W. TURNER” was entirely sold out on the day of publication, and many intending subscribers were unable to obtain copies, or were compelled to pay three or four times original cost of the book through their failure to order beforehand.
