A. A. Turbayne
Albert Angus Turbayne (1866-1940) designed book covers. Born in America he moved to England in 1890. His most recognisable work is perhaps his design for the Peacock Series published by Macmillan, which graces the cover of the PBFA members directory (pictured below).
His distinctive scarab, with which he signed his work, has been missed off of the directory due to cropping of the image, but you can see it lurking in the bottom right corner of George Morland by Sir Walter Gilbey (top) and amongst the gilt decoration of The Wye (below).
What is interesting about A. A. Turbayne is that he designed covers in more than one style. He was as much at home with Art Nouveau as he was with Arts and Crafts. The defining characteristic that links them all (apart from the scarab) is that they are beautiful.
Both The Wye and George Morland (the later is my favourite cover by A. A. Turbayne) are both currently for sale by Blueberry Books. If you would like to see further information regarding them please click on their photographs.
