Gotcha! It’s actually my The Ghost!
Anyway, it just kind of reminded me of some of his more sketchy sketches. (If his sketchy sketches were actually sketchy in the more modern sense… i.e. bad.)
I believe his method of haunting involves popping into a room (riding crop tucked firmly under the old arm), uttering a hearty “Morning, chaps!”, and proceeding to knock every available top hat to the floor with all the ethereal dexterity of the eternally damned.
