Maurice Tulloch (1894?-1974) illustrated several pony books, and numerous books on
sporting subjects. I have, as yet, found no biographical information on him, but
I assume from the dates of his published work that he saw active service during World
War II. It is probably that he spent some time in India: he was certainly commissioned
to illustrate several books on Indian subjects.
The pony books he illustrated are mostly done in a bright, sunlit style, but I think
his most succesful illustrations are when he moves away from that to a more realistic
portrayal. I particularly like his Jumping Jan, which emerged as one of the most
popular of pony book covers when I ran a poll on the Forum attached to this site.
Ponies in Secret is very unusual amongst pony books in having colour plates throughout,
as well as a colour frontispiece. The book instantly conjures up a distant world
where the sun always shone.
None of his pony books are impossible to find, as long as you don’t mind paperback
reprints. If you want the originals, with dustjackets, then The Impossible Horse,
Four Rode Home and No Place for Ponies are all now expensive, and hard to find. Jumping
Jan has increased in price over the last couple of years, but the other pony titles
are still reasonably easy to find.
