An anonymous artist

I happened to see an owner of the decorated motorcycle on my way to walk this morning saying he is doing good work. Then his speech vested into his artwork unlimited.
Finally, he gave me one of his work made by play, but it is nothing but an art. He wrote his name and his residence on the back surface.
There are many famous artists of contemporary art, but there actually exists an buried and anonymous artist like him, he must jump to the stage.
