As a fan of graphic design and typography, I particularly love seeing words painted on walls, signs, billboards and elsewhere.
So much so that I started a Words on Walls Pinterest board to collect my favourites.
To me, typography on walls, signs etc is an equivalent to public art and sculpture. You can get a sense of a city or country through them.
There's something about words painted on brick or metal which strikes me as very American. I took these examples on my trip to New York and Chicago.
