Which version do you recommend ?
If you plan to frame your map behind glass, I recommend the poster paper version. If you plan to frame your map without glass or you plan to pin your map to a wall, I recommend the laminated version. Normal changes in humidity will cause the poster paper version to sag over time if it is not mounted, such as for framing. On the other hand, normal changes in humidity do not affect laminated maps.
If you don't have wall space for a map, please try a folded map. I print my folded maps on special high-strength map paper that will last many years under normal use. And my folded "Essential Geography of the USA" map features an atlas fold that allows you to read across the country like you are turning the pages of a book.
