Below is the original Burke hardback first edition, which was illustrated by Sheila Rose and published in 1959
And this is the Dragon/Granada paperback reprint, which has a lovely cover illustration. It's not, as far as I know, credited, but if anyone can shed any light on the identity of the artist, I'd be grateful. I think it's my favourite of them.
This is the most recent printing, by Cavalier books, run by Christine's daughter. It's a perfectly respectable photo cover, but the Lost Pony is in fact grey, which is just about acknowledged by the Burke paperback, and is quite clear in the other two. It's a difficult science, cover illustration.
