This is an 8" by 10" color photo of Daniel Radcliffe, Emma Watson and Rupert Grint. I have double matted it to an 11" x 14" size with a white outer mat and a light blue inner mat. The photo was signed in London on March 13, 2006. You will receive the exact details on the certificate of authenticity issued by my company. I offer a lifetime guarantee on its authenticity or a full refund will be made.
