I've created a full scale Faery Tale Adventure map, which is 32,768 x 32,768 pixels in size! If you want to check it out, here's a zip file:

The full map eats up 8Gb of memory when loaded in GIMP, so beware! I have also included four quarters of 16,384 x 16,384 size each, that I'm attempting to upload to the HOL, and also the interiors.
Thanks go to Codetapper, who did the hard work and created a special Maptapper version for it.
