NH Hotels advertisement was placed on Iberia airlines headrests. On the back of the headrests you could see illustrations enjoying the different activites offered by NH Hotels: golf, beach, sauna, etc. When people sat they would see the illustration in front of them and just above the illustration's head you could see the hair of the person seating right in front as well, as if it were the illustration's own set of hair.
