This is a rectangular mug shaped like a section of brick wall with shrubbery and the Singing Busts from Disney's Haunted Mansion attraction.

The Singing Busts or Mellomen are a group of undead characters who appear in every version of the attraction except for Mystic Manor and whom act as the lead singers of Grim Grinning Ghosts in the Graveyard.

From left to right, the names of the busts are Rolo Rumkin (Verne Rowe), Uncle Theodore (Thurl Ravenscroft), Cousin Algernon (Chuck Schroeder), Ned Nub (Jay Meyer) and Phineas P. Pock (Bob Ebright).

This mug is glazed in blue and holds 22 oz. The back reads: "Happy Haunts Materialize and Begin to Vocalize".
