matte ivory glaze figural duck planter, 30s or 40s USA art pottery

Vintage USA pottery planter - a small duck, 5 1/4" long. It's a pink-toned ivory matte glaze, this looks very much like Hull pottery to us, though it's not marked.

It's been used, and has soil remains and some rubbed and worn areas to the glaze, with the finish worn away along the edges at some points.
