"I Come to the Spot" Street Art

I captured this photograph a year ago. It was located at the top of a sign not far from Stepney Green tube station and near to a church there, on Cephas Road. I was on my way to work on Brick Lane. The area is not too popular with street artists. I am not sure who is responsible for the piece. The piece has been painted onto a sign, and it reads "I come to the spot" and there is an image of what looks like a UFO floating next to the arrow. 

If anyone knows who the artist is, please leave a comment.
