Sgraffito Redware Vase

A redware vase with a sgraffito stylized motif of a eagle with arrow, also a motif of group of three figures. the figures look like they are possibly indians in a tree form.

The piece was wheel thrown, in a vase form, with a clear glaze.

Signed on the bottom, O A.

There is a small old repaired flake chip on the bottom rim of the vase.

I would love any help in identifying this vase, age, and possible value.
