This mug depicts a tiki idol holding a book, on top of a barrel of dynamite with a fuse lit by a candle.

From Lost Temple Traders:

"Welcome curious travelers! The idol we present for you this evening is as peculiar as any we’ve ever come across. Part New Orleans voodoo and part island deity. One thing is for certain, when you imbibe from these haunted spirits, the room will feel like it’s stretching. This is the pre-sale for the Limited Edition 250 Ghost glaze variant Haunted Spirits: Dynamite mug."

This is the Ghost edition, which is primarily light blue with a red wiped finish. This edition was limited to 250, but is not numbered. Other editions include a red sangre glaze, and a brown glaze. The design is a "tikified" play on one of the stretching posters in the Haunted Mansion attraction at both US Disney theme parks.
