custom made decor

[Eidolon]

What I think of as my 'cinema room', is a bit of a low-budget compromise, and futher limited by ongoing problems with my house. I'm trying to do smaller things to keep me a bit positive and ticking over in the meantime until the serious structural work is udnertaken.

I have one wall with three framed movie posters, and a space at the end that is intended to be interchangeable between another poster frame, and a 1980's video rental store plastic rack that I currently have there.
For various reasons, I want to do something above the racking unit, and have decided upon having a 'Coming Attractions' sign that will wall-mount just above the racks. Rough size will be 60cm by 13cm.

There's a printer by me who will do a nice sign on Foamex at a reasonable price. But I'm not sure where to begin on ideas for how this one should look. Has anyone else got/made a sign of this type of nature?
