a.k.a. Irwin The 2nd Skull Mug Bone White
This is a skull mug in bone white glaze with black sockets and black wipe glaze to pick out detailing. It has heavily pronounced cheekbones that sweep towards the back of the head and come to a point, almost like rear fins on a classic 1950's car. This is a larger version of the previous Irwin Skull mugs.
