How to cover a poster to protect it and hang it on the wall?

Question from Sandrine:

Answer: opt for a very large sober frame

Hello Sandrine, why don't you just choose a sober enough thick black metal frame with two panes and no bottom, big enough so that you can see the wall (colored?) All around the poster, once hung ? This solution will certainly be more economical and just as satisfactory for your poster. Another solution, also a little more expensive: it is the "so-called American box" which has no glass. These American boxes are the trendy and design solution used in a number of photo exhibitions but with a beautiful poster, the rendering can be eloquent! You too, send us your decoration question
