I bought this Mug when Royal Copenhagen was still being produced in Frederiksberg just outside of Copenhagen. It is a Royal Copenhagen Blue Fluted Half Lace Mug. The logo was left off the bottom because it was a custom product for Japan.
The Kirin Brewery commissioned the Mugs and Kirin needed the space to put their logo on the Mugs. I still have around 20 of them. It is a very special piece that nearly never comes up for sale. It measures 5.5 inches high and has a diameter of 3.5 inches.
