Olivia Muus knew she was onto something after taking a photo, with a friend, on a trip to the National Gallery of Denmark. It turns out, manipulating an old painting, in the form of a selfie, can give a character’s facial expression an entirely new meaning. So it was then that a Tumblr account was born and Olivia could continue her cheeky art project and encourage others to submit their own museum selfies. The result is downright amusing and hilarious! The next time you’re at a museum and find yourself in front of a historic portrait, maybe try your hand at your own #museumofselfie. But remember, no flash please.
