This is a mug styled as a rocket ship with a tiki face for Hidden Harbor's 8th anniversary.

From Hidden Harbor:

"Mugs were sculpted and produced in Santa Cruz, California by Mikel Parton aka MP Ceramics, in two limited-glaze editions of 50 mugs each, each individually numbered, with a certificate of authenticity included. Each mug stands a towering 10 inches tall (be sure to measure your shelf height if unsure!) and holds approximately 16 oz. of your favorite tropical cocktail."

Hidden Harbor logo trees and waves on back.

These were produced in either "Galactic Green" or "Sky High Blue".
