Charles Allan Gilbert (1873-1929) was an American artist and illustrator. Gilbert studied art in New York City and Paris. He is most famous for his illustration All is Vanity (1892), an optical illusion. Created when Gilbert was only eighteen years old, the drawing depicts what appears to be a large grinning skull.
