From 2017 and onwards, all of my Friday Enhanced maps include unnumbered images. There is a layered PDF and a zip file with all relevant images. The map images are broken down as follows:
White background. numbers, secret doors/DM only icons
White background. numbers, no secret doors/DM only icons
White background. no numbers, secret doors/DM only icons
White background. no numbers, no secret doors/DM only icons
Black background, numbers, secret doors/DM only icons
Black background. numbers, no secret doors/DM only icons
Black background. no numbers, secret doors/DM only icons
Black background. no numbers, no secret doors/DM only icons
As of this year, I've included the above with the additional option of no grid versions. That doubles the map count from 8 to 16.
Cheers,
