It can fit in a large Ikea Ribba frame if you use the mount provided. A very small part of the picture is lost and you can't see the number/embossed stamp but if you are on a budget it can work. That's actually how I bought mine, Roxy, but I don't like the frame, as it doesn't fit in with our other framed items (e.g. it's a natural/pine colour and the others are black, perspex/plastic instead of glass etc.), plus, as you said, the limited edition details were masked by the mount.
If I decide to sell, I'd offer the IKEA frame as a freebie, if the buyer wanted to collect (offered it to my local picture framer, but he told me he leaves them outside his shop as scrap/freebies!).
Thanks to you & J.O'B, as always, for the background info.
