"A Beautiful, Escapist Map of “Fairyland,” Published in Britain at the End of World War I . . . ."A map which mashes up all sorts of make-believe geographies, not leaving out even "Below These Starres Lyeth the Lost Citie of Atlantis . . . ."
One can be lost in this map for hours, zooming into and enlarging its many regions.
See it here, to zoom in and out. The image above won't do for that.
The map itself is in the holdings of the Library of Congress.
