This is an extremely rare mug! It is a taller than average measuring over 5 inches with artwork on its front surface depicting a black & white cat wearing a necklace.
Also has a ring of blue and black trim wrapping around its rim on the exterior surface.
Although no markings are present, based on its style I strongly suspect that this mug was manufactured by Otagiri.

There is a raised area to the right of the handle on the rear surface, please see the 360 photo.
