There is Le Dernier des Mohicans(Last of the Mohicans) and L'Espion (The Spy) both by Fenimore Cooper .
They are part of series published by Boivin for young children who published 32 in total between 1922-1930.
The front covers are in an attractive deep red and beige, and inside there is a wonderful colored print. Inside the books the text is in French with black and white illustrations.
The books measure 15.5 cm x 24.5cm and have 95 pages each.
Condition is good although L'Espion has slightly wrinkled front cover , see photos for idea of condition.
I have another pair of books from the same series to list. Please convo me for details.
