A folded poster without vertical folds???
When a poster only has three horizontal folds and no vertical ones than it’s usually a Disney poster. Because this is what they call the Disney Fold (Disney tended to fold posters that way a lot). We donĀ“t know if they were tri-folded and then shipped flat or rolled. We, personally, would pay a bit more for a tri-folded poster because it looks a bit nicer.
