That said, these are obviously better quality because that artist has probably had far more time spare to put into them, of which any number of the artists here could do if they had the time, including Zacchaeus. These particular maps seem to line up along with the labelling of the adventure's isometric maps themselves, and they effectively provide the same purpose as Zacchaeus' ones.
The map count is the same, though the outside one is merged with one of them and another has been done elsewhere.
