Dimension of the display must be conserved ? (and we only have to create design for each face).
Must we design the face behind ? (not see on the display).
Did there is any logo ? (if yes, please join an EPS or illustrator file).

Thank you.

Dimension of the displaybox should be conserved because we plan to put in that displaybox 18 smaller boxes with posters (3 rows with 6 boxes). But for now we have only 2 of these displayboxes , we plan to order more, if you have some ideas about dimensions, we are open for any suggestions (dimensions are not carved in stone).

Yes, there is back face but we feel that designers should concentrate on front face design primarly, beacause this displaybox is going to be displayed in shops with some other (competitive) product boxes, and in most cases, only front side is going to be visible. Back face could be with the same design as front face, just with different poster picture displayed.

We are not interested in logo design, but there is a possible logo we are using - it is a signature of the artist who created these posters, but I couldn't upload it because of the 5 file limitation. You can use this logo for displaybox or for sticker.

you can see logo design here - http://i44.tinypic.com/2mhcz07.jpg

ok

So did there is any example of visual you like, some example permit to start in a good way.

uh, that is a hard question. I just know I'm stuck and have no ideas, I would like to keep the design simple, minimalistic, so the potential customers know what we offer, and it is not mandatory that we display a picture per side, you can use just a detail or whole picture. The problem is I couldnt find online nothing similar as this displaybox for posters, so I have no examples, sorry.
