This is a fog cutter shaped mug with a Hawaiian drum look to it that is encircled with Hawaiian petroglyph images. It is also marked "HB Things Hawaii" on the bottom. Polynesian Pottery created a version as well with their marking of the double P. It’s likely that Adele Davis (who sold PP to Daga), had extra molds (so she could pour more than one at a time) and since she continued to make mugs and teach it's also likely that HB Things Hawaii obtained one of the molds as well. The Polynesian Pottery version of the mug is pictured on the cover of Waikiki Tiki by Phillip S. Roberts.
