Picasso self portrait
The best wood for carving and painting on is oak. Oak is a tree that has spiral arranged leaves and smooth margins and the family name for th oak tree is fagaceae.
Petra thought to search the Castiglione's tree house for the painting because she remembered reading about a tree in a book about Castiglione and struck by the coincidence that their last name was Castiglione too.

There are a number of trees to fit this description, Birch and Beech to name but two.
