This mug is shaped like the hooded skull of the Grim Reaper. This design originally came in two color combinations: black hood and bleached white skull, and the "Skeletor" version with a yellowed skull and purple hood. This version was issued on Saturday July 18, 2015 from 6 AM to 10 PM as part of the random "Day of Gold" where different gold glazed versions of Munktiki designs were made available throughout the day -- similar to the Black Friday event hosted previously.
