Early Folk Art American Two Sided Framed Military Drawing With Map

This unusual set of drawings in a double sided frame came out of an old New England Estate in a Beacon Hill, Boston home. From what we have gathered, they are hand-colored drawings of some sort of dignitary drawn on one side and a perspective drawing and a map of islands on the other.
The perspective drawing shows the peripheral vision of three eyes. The map shows two islands, each with an American style house with chimneys and native pine trees.
They are framed with glass in a two-sided wooden frame. The side with the man is matted.
Site line of man measures 8 inches tall x 5.75 inches across.
