Wooden name sign for nursery

I bought a wooden name sign for my baby girl’s nursery. I’m just curious what I should use to hang it up? It will be on a wall away from the crib so if it falls it’s not a big deal, but obviously I’d prefer it to stay up. I don’t really want to put any holes in the wall, so what can I use to hang it up? I also don’t want to damage the paint on the walls, so if I use something with adhesive it needs to be paint friendly. It weighs approximately 2lb. Thanks!
