I suggest using adhesive vinyl media with paper backing. You may use it as a regular poster attaching it to a wall with thumb tacks or you may remove the backing paper and apply it to a wall as a vinyl sticker (wall decal). Vinyl is a plastic film which is much more durable comparing to a regular poster paper. Also we use solvent based ink to print on vinyl which is usually used for outdoor advertising and such an ink is more sun / UV stable.). One 24″x30″ adhesive vinyl poster with full colour print is $25.00.
