Frame Fitting

Do you have a cool poster like me hanging in my office. Non-standard size and the frame does not fit. Suggestions?
I could get that As framed but that seems a bit excessive given the Ecomony at this time, and you know a little about the top for just a lineup of rock. It's nice and although we love do more than just the basics to the wall and I'm not a child.
You could try to get some spray fixative and join a large piece of cardboard foam core cut to size. Attach picture hooks on the back or sides of board for hanging. If you want to get more detailed and heavy-duty with her, you could try attaching a piece of Plexiglas cut to size on the poster and board for a finished look.
