Answer 1

Of the contemporary artists who are exploring large-scale drawings on walls, Gary Simmons specializes in the medium of chalk.
He is an American artist who often uses cultural stereotypes in his art in order to convey a specific message. He is one of the rare artists today who uses chalk in order to do that, drawing immense images on a black background which astonish his audience. I've attached an example of his work.
