From Hidden Harbor:

"This is the teal version of our new rum barrel mug, designed by Tony Canepa and sculpted and produced in the U.S.A. by John Mulder and his team at Eekum Bookum. This is part of a limited glaze-edition of 50 mugs in this glaze combo, each individually numbered. Each mug stands approximately 5.25 inches tall and holds approximately 22 fluid ounces."

This is Glaze #2. Glaze #1 is a "Barrel Aged" Brown. The Brown version almost sold out at the release event and was not subsequently put up for sale online like the Teal version.
