Jane de Bargue Hubert
British author who only appears to have written one pony book about a unusually named piebald pony. It is a very attractive looking book but it is also an extremely hard book to come across and usually expensive - so it is doubtful most collectors will be adding this author's one and only book to their shelves!
I would be interested in finding out more about the author - if you have any information about her I would love to hear from you.
NB - Thanks to Sara Beasley for the pic.
