Bert on the rooftops.
Bert has a number odd jobs. He is a chimney sweep and also plays in a one-man band as a street musician. He is an old friend of Mary Poppins and is featured in the opening scene of the Mary Poppins Disney film.
Bert is played by Dick Van Dyke. Bert is an artist, drawing images on the sidewalk with chalk, that Mary Poppins and the Banks children eventually jump into for another magical adventure. At the end of the movie, Bert is selling kites near the entrance of the park.
