Excellent Kid Made Cut Paper Creature on Purple Construction Paper

The last one from a quartet of kid made cut paper works I purchased a few weeks ago from a dealer at Brimfield, which struck (strike) me as quite sophisticated things, and, especially in the case of this creature, super playful too. A turtle I presume (?) with excellent faceted shell---perhaps a sea turtle, just about to swim out of the frame?! With tiny ink drawn eyes at the tip of the center triangle of its head. Good pointed in any direction; ah, the brilliance of children.

9" x 6" and in good condition, with a bit of wear/tiny loss to two corners as documented.
