Promoting a font for the tombstones seems to be a bit problematic.
How will you advertise it? Will the target group recommend it to their family members and friends? Will the enthusiasts of modern design remember about it when they will need it? After how many years will it happen?
Anyway, if you fancy a touch of runic inspiration, military decisiveness and a fresh minimalist finish, Wrocisław might be the font for you.
Free for personal use and actual tombstones.
