The Hawaii 50th Anniversary Mug was originally designed by Brad Parker (aka, Tiki Shark) for Tiki Farm. The original features two Kus back to back with a Hawaii quarter embedded in front and read: "50 Years of Statehood 1959-2009" on the back. This unauthorized version to promote DeKuyper is smaller, one-sided, and has a circular spot for the quarter but no quarter included. It reads: "DeKuyper Anno 1695" on front base.
This was one of three tiki mugs produced at this time for DeKuyper (the others being black and white), and each is labeled "DeKuyper Anno 1695" on front base. No maker's marks, however.
