Query: The easiest, cleanest way to hang posters!

The 3M Command Poster Strips are hands down the best solution for hanging posters or other light art on your walls. Forget about nails or screws that leave holes and forget about traditional double-backed tape that leaves nasty tape gunk on the wall after you remove the poster.These 3M strips are easy to apply to the regular drywall, plaster or even brick and hold your posters or photos to the wall VERY securely. When it's time to remove the art from the wall you simply pull down on the pull tab and the adhesive comes right off without leaving anything behind.This is perfect for dorms or apartments where you'll only have artwork up for a little while and it's also perfect for home owners who don't have to mess up the walls in their house. Even better, these things are reasonably cheap. My wife and I purchased a bunch of these after we discovered how easy this makes it to hang stuff in our house.
