Vintage USA Pottery 3 Pigs Planter Backside Looking Over Fence McCoy? Shawnee?

Is it Shawnee, perhaps McCoy or ... who knows. This cute pig planter is vintage for sure, has 3 pigs on their hind feet trying to look over a fence. It's a creamy almost peach color, salmon might be a better description. Stands approximately 3.5 inches high and 6 inches wide. It looks like it was being used as a pen holder on the inside. I did my best and got out most. If you don't need a planter, well there is another use for it. It's got Farm House, Country vibes. no chips or cracks. Sold as shown, please see all photos.
