A tweet of a chalk drawing of Elsa from Disney's Frozen on a classroom chalkboard has been garnering a lot of attention, and the artist behind it is apparently not a student.

A high school student in Japan tweeted the drawing on his classroom chalkboard, and right away the comments came flowing in. What started out as just a little fun ended up making the rounds on the internet, and eventually the tweet got taken down. (Maybe Disney found out about it!) Either way, the drawing is pretty amazing and the artist is obviously talented. From the looks of it, it seems as though it was probably drawn by a teacher, possibly an art teacher. But so far, no one has claimed responsibility. Next to the drawing of Elsa is a little motivational message for the class...

"Be yourselves and take on challenges!"

Watch a 400-year old alien hunk fall in love with a beautiful actress in My Love from Another Star.

Now will the mysterious artist please stand up?
