> Hello, my name is Christopher Benson from Atlanta, I was looking for some artwork online and I found your contact while searching. I will like to purchase one of your work for my wife as a surprise gift for our 20th anniversary. I'll need pictures and prices of some of your art work which are ready for immediate sale within price range of $1,500- $2,500. I hope to hear a lot more about any available piece in your inventory ready for immediate sale.
