Molino

All those which were illustrated by Bertram Prance have retained his illustrations for these editions, although he is described at least once as Bertram France ! Later books are illustrated by Spanish artists.
There are eighteen of the Lone Pine series listed here, which is all that have fallen into collectors' hands to be described.

As can be seen below, the earlier covers were all produced by the artist Pablo Ramirez, replaced after his untimely death by Badia Camps
