To design Mr Black, we used old ('70-'80) dry transfer lettering sheets that were used by my grandfather who was a military cartographer. We had only two almost used-up sheets. The letters didn't transfer so well but we liked the way they were damaged.
All of the characters have a very high resolution so they can be used in a large scale. Mr Black doesn't have lowercases but has up to three alternate uppercase for each letter. Checkout Mr Tiger if your looking for lowercase letters with the same distortion effect.
We designed it for our book for children, “Who eats Whom”
