more to add on, this artwork is actually done on the couple's honeymoon, its rather sacrificial of them to stage a protest in such a "soft and non violent method" and it does have an aesthetic purpose. Its not an artpiece to look and gaze at, its an art piece, or performance art to be detailed, that should spark deep thinking, that the protest will rewind in the minds of the viewer.

its an act that is totally different, in the video, people were taking pictures, writing notes of praise about them.

its a protest against war, their outfit and the john lennon's hairdo reminds me of the Hippy people, promoting love and curbing war....
