This charming series was used in the cabins of West Virginia State Parks, and some of it was also sold in park gift shops. Each piece had the seal of the State of West Virginia, but select pieces (most commonly plates) also had larger images of a deer, quail or log cabin.
It was made by both Carr and McNicol China.
This is a mug made by McNicol with an extremely hard-to-find handle style that we more commonly associate with the circular handles with ridged attachments made by Fiesta, though I've also seen it used at times by Jackson China.
The mug is about 4 1/4" wide, including the handle, by about 3 3/8" high.
Condition is pristine for this piece; it looks unused.
