Randy Asplund, the artist who did the map, has posted it up so I'm linking to it here.
It's really fun to see my world -- exactly as I originally drew it, based on Kathleen's Much Better redrawing of it -- there in a high-quality map, waiting to go into my own book.
I first drew what became the main continent of Zarathan back in 1978. It's changed since then, but the basic physical outline has remained pretty much the same for 30+ years.
