This is a Full Colour photo measuring 8" x 10" (approx 20cm x 25cm) signed in black. 

This is not a print or a copy, but an actual item hand signed in person by all 4 band members. Nice clear undedicated and undated set of signatures.

Complete with Certificate Of Authentication (often abbreviated to COA). All items are 100% Lifetime Guaranteed Genuine.

8" x 10" is an industry standard size for photos. It looks great as it is but if you wish to frame it then you'll have no problem buying one "off the shelf" in this size. We've seen these for sale in Tesco, Argos as well as many other stores.
