Ideas for displaying an odd shaped thing that would cost £££ to frame?

[VitaPuffin]

I've got a lovely old music chart that I want to put up on the wall, but it's 2.5m wide and about 30cm tall, so an odd shape. I've looked into framing it and it would be at least £200 :o

I don't want to just blu tack it up - any bright ideas? Sandwich it between two bits of perspex maybe if I can get them cut to size (or would that cost as much as framing)?

that was supposed to be a not a

We bought a bit of perspex to put on DS1s desk, he'd put old 1960s comic pages underneath. It cost about £25 from memory (it had rounded corners and so was a bit more than the standard price).

Sounds like perspex could be the way to go, thanks atticus :)
