If you mean me then I make the frame to whatever size it needs to be. You just provide the shirt and a few ideas. See if this link works to have a look at the sort of thing I do. If you are looking on a phone you may have to go on to the "recently added" tab to open up the 9 photos. https://davidsunderland.co.uk/apps/photos
My mate Neil Richardson does. Hes the artist and blowk who has a section in the matchday program. He's just framed loads up for Mowatt, O'Brien and a few other players. He'll provide the frames. Message me if you need his details.
Do you custom displays? I collect movie autographs, most of them on 8x10's and would like to a few displays made up at some point(for example, say 4 or 5 8x10's from a movie, in a nice matted display)...
