Lettering is the art of drawing letters over every surface with every tool. The graffiti is the best urban art way to understand this concept. Street artists who paint murals highlight their letters and words with the best shapes and colours they can make.
"Be Strong" is a illustration which you can get as adhesive vinyl sticker. A nice group of letters and words in English and Spanish made by hand which give a natural wealth on desings. It's a good element to decorate your wall, door or cupboard.
