I have a painting with a signature that I can not take place for the life of me, help?

I have a painting with a signature that I can not held for the life of me. I think the signing said Corsi. But it is a first that I am not able to determine. The painting is a pot of sunflowers. It is especially many shades of yellow and brown earth.

Many artists over there recognized the name Corsi, but none of them are known to still life. http://www.askart.com You can take a picture of a fine-art auctioneer of assessment or photograph (with a closeup of the signature) and send images to http://www.allexperts.com They are very good, and free (but they do not comment).
