Up to D&D
Probably around 1993, I drew these pictures to show players while running T1 The Village of Hommlet. I recently came across them & decided to scan them on the off chance someone else could use them.
Someday, I may try to filter the grid out. (I'll either have to write a program to do it or just play out with the Gimp for a while.) After that, it might also be good to enhance the contrast.
Anyway, if you find them useful, try to let me know.
