This is a super nice Mickey Mantle (NY Yankees) restaurant ware mug / cup. I believe he had this restaurant in the 1960’s and 1970’s. This china was produced by Shenango China.
This mug is in excellent condition. I see no issues at all. Take a look at the pictures, and if you have questions, please e-mail.
***One of these sold on E-Bay for $95.00.
