I stuck the poster, onto the wooden panel of the wall, with some sticky tapes. It held for 10 minutes, then it fell down and the glass broke. I stuck it up again. This time it was much lighter, as there was no glass - just a light silver frame. I put some more sticky tapes, to be sure it will stay on the wall FOREVER, but .. off it went again, after just 15 minutes. Luckily, I took some photographs, just to remind me to try it all over again.
