Inspired by a font used in an elevator plaque (discovered on my Instagram feed, thanks, @jo_forresten). I lived in an apartment building in Olso where we had a sign like this one. Based on the letters in the plaque I have created the remaining alphabet to complete the font.

Mr. Otis (1811-61) was the guy who invented a safety device that prevents elevators from falling if the hoisting cable fails. I thought he deserved to name this font.
