I rated this low because the title is misleading. This is an encyclopedia of Xanth, not a visual guide. It does give a lot of information on all things Xanth, but most of the items don't have drawings, the few drawings that are there are black and white pencil sketches, and they're often inaccurate--often don't match the descriptions in the books. This is by no means a "visual guide", but it does have a lot of information on Xanth and may be of interest to a devoted fan of the series or a collector.
