From Katiki Classics:

"The first mug in this series (Bucket No.1) is a tribute to the legendary Tiki Bob's in San Francisco, California. This mug is adorned with the classic Bob logo [designed by Alec Yuill-Thornton] and font that were used on their marketing materials and advertisements. These mugs are a series of modern tributes to the classic vintage bucket mug. These vintage bucket mugs were custom made for dozens of establishments starting in the 1960's, but there were a few notable tiki bars/restaurants that never had them produced. So we're reimagining these bucket mugs as if they actually were used at these legendary places. This mug is made of stoneware and is 100% hand-glazed by Will Fugate of Tiki Classics. These mugs are slightly larger in size than the vintage bucket mugs and hold approximately 24 ounces of fluid."
