Horse & Pony Books:
SOMETHING TO JUMP FOR
(COUNTRY LIFE 1960)
ILLUSTRATED BY JOHN LOBBAN
SUMMARY: Traditional pony story. Tess works at a stables owned by a hard-nosed dealer. She loves the mare Dancing Lady and determines to save up enough money to buy her by riding in shows.
I don't think this was ever reprinted. Reasonably rare, although not extremely so and is not usually that expensive to buy. Nice illustrations.
