Kelliegram bindings were an innovation of the English firm of Kelly & Sons. Often, one of the engravings inside the books was reproduced on the cover with leather onlays (a thin piece of leather glued on top of another piece of leather) or inlays (a thicker piece of leather glued next to another). This technique was used by other famous English binders, such as Riviere & Son (see the two next bindings), Bayntun, Root and others.
Here are four examples of Kelliegram book bindings, from left to right, top to bottom:
The examples below show the illustrations used in the cover design.
The Ingoldsby Legends, by T. Ingoldsby, illustrated by A. Rackham. 1930. The pictorial cover is a copy of an illustration. Arthur Rackham, Kay Nielsen, Edmund Dulac, Sulamith Wulfing are considered among the great illustrators from the golden age of illustration during the first quarter of the 20th century. Others included W. Heath Robinson, Eric Pape, Maxfield Parrish, Orson Lowell, Franklin Booth, Elizabeth Shippen Green, J.C. Leyendecker.
The Pickwick Club, By Ch. Dickens, illustrated by C. E. Brock. 1930. The cover is also a copy of an illustration. The amount of details shown on the covers is simply amazing and calls attention to the craftmanship of the binder.
