Biographical information on Marcia Lane Foster is hard to find. She was a prolific illustrator, working on Pamela Brown’s later works, and Viola Bayley’s lengthy Adventure series, but her work in the pony book genre was unfortunately small. I love the way she includes the spine of the book in her jacket designs, particularly for Christine Pullein-Thompson’s We Hunted Hounds, where the hounds are seen galloping along the spine, with the rest of the field on the front. I also like her use of white to delineate in Mary de la Mahotiére’s Round-up On Exmoor.
She wrote a few books, which appear to be early readers, all written for Humphrey Milord and the Oxford University Press, and all published in the 1920s. Her Let’s Do It ((1938) is a collection of her sketches, and includes a section on the Pony Club.
Finding the books: all the pony books she illustrated are easy to find.
