CSI Original Cast Signed Photograph For Sale

This listing is for a hand signed photo of the original cast of CSI which I obtained from a private seller in 2006. It came with a certificate of authenticity at the time and I have confirmed the signatures match those of the actors and it is clearly visible that these are signed on the photograph (I've tried to show this in the pictures but the camera isn't great at picking up the colour distortion of the inks when looked at from and angle).
This has been stored within an opaque folder on a plastic pocket since I have had it and never on display.
Any other questions, feel free to ask.
