In 1906, Clara Elsene Peck Peck married British-born illustrator John Scott Williams (1877–1975)...Peck and Williams shared similar styles, leading the two to occasionally collaborate on illustrations together. These works were signed with the first initials of their last names, "P W". Some of Peck's works are also credited as Clara Elsene Williams and the press sometimes referred to her as "Mrs. John Scott Williams". (From Wikipedia Article about Clara Elsene Peck)
John Goss's monogram on his book cover designs was a sans-serif G, with the bar extending inward into the counter.
On his illustrations and only a few covers, he also used a monogram that consisted of a G intersected by a J.
Could this be John F. Earhart? The monogram used is the word EAR inside of a heart, after all!
He is also referenced in the photographic credits of the one book associated with this monogram.
From the collection description:
" Jarndyce has specialised in 18th and 19th century English Literature and History since 1969. Most of our catalogues include three-decker novels, first editions and reprints of Victorian fiction. Our most used bibliographies are Sadleir and Wolff.
For most of our forty years in business we have also bought and sold major and minor poetry published during our period. Libraries have become increasingly interested in 'background' verse by minor poets, their writings reflecting the trends and fashions of the century. Indeed, Stanford purchased a collection of minor poetry from our good friends Chris and Michelle Kohler.
Partly as a response to this widening interest, we decided to accumulate 'minor' one-volume novels - from a period when the mainstream was dominated by two and three deckers and novels published in weekly or monthly parts. The total number in the single volume novel collection has now risen above 2,000 with just under 1,500 'Not in Wolff'. It is both a remarkable collection of minor fiction and a history of 19th century publishers’ bindings."
Originally from Glasgow, Duncan relocated to London sometime in 1899 or so. Not much is known of him in the literature, but he seems to have been primarily a designer for books and greeting cards.
Partridge was the principal cartoonist for Punch magazine. He was primarily an illustrator, but some of his illustrations were used as the basis of the cover designs of the books he illustrated.
