A number of people have noted (
here, among others; but this is not the first mention) that Wanda's room looks different in
Erfworld 74, panel 4, than it did in
Erfworld 27, panel 2. Specifically, the demon skull over the archway dividing the room, the candlestick between the bed and the archway, and the dressing screen on the right-hand side are missing in the more recent panel. As for the rest of the decor the matter is moot, as it is not visible from the viewing angle in one of the panels.
Now, this is probably poetic license:
the bareness of the room reflects the forlorn state of Wanda's mind. However, a number of posters have voiced other ideas, from a simple continuity error to a result of Wanda's upkeep costs having been disciplinarily cut. I'm halfheartedly listing this as a blooper. If anyone is strongly opposed, let us have a piece of your mind.
