Does anyone know where to get a huge klip frame or similar?

I have a large poster that I want to keep clean and rest against wall so was thinking of getting a large klip frame for it but cannot seem to find any poster sized. (Size: 19 1/2 x 27 1/2" : 500 x 700 mm) Please can someone suggest where I might go to get one of these? Thanks very much.

I've seen them.in the Pound shop and 99p shop. Can't remember how big tho. Google stationers in your area?

I saw some in my local The Range last week.
