Yup, that 1890 map is one of the ones I was looking for. 1890 is a fairly significant VSF year as far as I'm concerned, it's when the Atlantis campaign is set. Knowing it's by Giovanni Schiaparelli will presumably make it easier to hunt out a larger image on the web if there is one...
On the 'other' website that is now lost in the aether, I'm pretty sure that I remember that map, a modern map, and a composite of the two were all together, so you could use the Victorian ideas about Martian geography (Martography? Areography?) in the context of the actual topography.
