This is a beautiful planter from McCoy's Corinthian Line! It measures 9 1/4" long, 3 3/4" tall, and 4" wide. Planter is in a beautiful matte white color and is marked on bottom: 2003, USA. Planter has some small dark spots on interior bottom that appear to be production as they are under the glaze. Upper rim edge has 1 super small place that could be a "ding" but that I honestly believe to be a production glaze skip. There is a very small "ding" on one of the diamond designs -- all are of no consequence.
The Corinthian line consisted of 5 shapes and would seem to be an easy line to collect. It is not. For whatever reason, the pieces are few and far between and the matte white pieces seem to be especially difficult to find. In my many years of collecting, I have only found a few pieces in this color from this line.
