A hand sign from our Hand Heart Alien Sticker is a gesture in which a person creates a heart shape using their fingers. The upside-down hand heart gesture was noticed in art more than one hundred years ago when Italian artist Maurizio Cattelan and American philosopher Chad Buelow created an art image of the gesture as his first artwork named Family Syntax. This gesture became extremely popular in the early 2010s on social media. Aliens know about this thing too. They know about everything.
