C-3; Black with blue and red splotches.
Truly a Lost Ku...archeologically rescued from within the dusty tomb of Bosko's warehouse! 6 - colors available and 2 of 3 each were sold at eBay auctions to highest bidders. Bosko & Truus kept one of each color.
This black mug with red and blue glaze throughout was designed and manufactured by Bosko. It is a stylized Ku with diamond shaped eyes, a triangular nose and roughly dogbone-shaped mouth. Lost Ku was glazed in six different colors, and only three of each color were made for a total of 18 mugs. These were sold through ebay.
