British talented artist Mr Doodle (whose real name is Sam Cox) was born in Kent, England in 1994. With a marker pen, he has swept the world with densely laid out yet simple graffiti lines. Mr Doodle's works full of British hippies and humor have also won him numerous fans. In his graffiti world, inspired by contemporary popular elements or daily life experiences, a variety of strange characters, symbols, vivid fantasy and stories present his cosmology, it is also filled with a range of novelty, fun, joy and uniqueness.

Mr Doodle "Doodle Guitarist" is drawn from the legendary art master Pablo Picasso "The Old Guitarist", which is one of his classic paintings from the "Blue Period", mainly monochrome in gloomy blue hue, sometimes with somber themes, such as prostitutes, beggars and drunkards, etc. The character in the painting is dreadfully skin, who sits cross-legged and looks paralyzed on a brown guitar, appears to be so exhausted, the artist primarily explores poverty and misery, and confines himself to a sense of melancholy. Since the School of the Art Institute of Chicago acquired this painting in 1926, it also became the first American museum to permanently exhibit works from Picasso. Mr Doodle is taken from this painting as the prototype, the whole picture applies bluish tone as background, which seems to be suffering yet full of wit simultaneously. Mr Doodle reinterprets his own graffiti art with his distinct and new personal perspective.
