Removing Bends/Creases from a Print

[DampCat]

Anyone got any experience with this kind of thing? Obviously despite all the "Please dont bend" begging and hard cardboard inside the royal mail remain a bunch of ballbags and my print has returned complete with multiple bends. They're not super creased (Like where they go white through broken ink) but they're noticeable.

Does anyone know of a non-destructive way to remove light bends? It's a unique one-of-a-kind piece so i want to be as gentle as possible. It will be mounted with a fascia between it and the glass so I cant really rely on framing to remove them.

Thanks

Edit : It's a photgraphic print on standard Photo paper, although it's quite large (~A4 ish)

Its not an option as it's literally unique (signed and personalised). Its not beyond repair or anything, I just dont want to damage it further in trying to repair it.
