Mounting tack can rumple and damage paper at the contact points, and is recommended only for thicker material posters, or those mounted to a backing.

Tacks will leave a small hole in the poster, and in the wall behind it. Do not use this method if you don’t want to damage your poster. Staples can also be used, just open up the stapler all the way and place its head against the poster before pushing it in to staple it. You could also push sewing needles through the corners of the poster and into the walls—the holes will be nearly invisible when you take the poster down.

Avoid using strong magnets, so as to not crumple the part of the poster beneath it.
