Vintage Brown Pottery Bowl

Mixing bowl with the bottom marked as USA 8 inch, and I believe it was manufactured by Monmouth Western Stoneware. It is 8 x 4 inches. There are no chips, cracks or breaks, but has light utensil marks. There are several manufacturing flaws. There is a lot of glare in the photo and do not mistake those areas as loss to the finish. The angle of the image does not not show the 3rd band is tan, the same color as the rim. I need your zip code to calculate the postage.
