Rare Vintage Early Rae Dunn M Studios Cat Mug Meow Mug White Ceramic Mug

Rare Rae Dunn M Studios Cat Meow Mug. The mug has crazing throughout, I'm not sure if it is suppose to be part of the design but the mug doesn't have any chips or cracks and is in solid condition. I have not been able to find another one, it would be a great addition to a collection.
