This is a variation of different artwork done by multiple unique artists. This collaboration of photos demonstrate different ways artists use to demonstrate their opinion on same sex marriage. If you look close enough you'll notice that theses photos all come together by having things in common with one another. The first one being that most of them include the gay rights flag or cheery colors I would say. The second one being that they all include two people joined together and look like they're in love. The third concept is marriage using the symbols of proposal and wedding rings.
