An artist named Aaron Zenz has taken on a really amazing task over the last couple of years.

Zenz sent out a call for kids all over Michigan to send him their monster drawings and he turns them into great pieces of art. He’s received over 17,000 submissions and the pieces are on display outside the Children’s Museum in Grand Rapids, Michigan. Learn more at ArtPrize.
