This is a mug shaped like a cresting wave. The back reads: "Three Dots and a Dash, Chicago, IL." Used to serve their original cocktail, the Surf Report, described as a blend of gin, cucumber, anisette, and mint flavors. Manufactured by Munktiki Imports. Designed by Darick Maasen and sculpted by Kosart Studios.

This first edition was glazed in dark blue and white. The second edition was glazed in light blue and white. There is also a Wave Mug II which has a different sculpt -- a wave carrying along a floating mine.
