Okay Hollywood, you've got a pretty impressive sign. But this just might have you beat.
This bad boy has been built on a hillside in North Korea, in honour of the country's new leader Kim Jong-un.
It says "Long Live General Kim Jong-un, the Shining Sun!". And yes, there really is an exclamation point at the end.
Not only that, but the message stretches more than 1,800 feet (548m) and the characters are 65 feet high (20m).
In fact, this thing is so big you can see it on satellite images.
Kim Jong-un took over as leader of North Korea after his father Kim Jong-il died in
He was quickly referred to as the "Great Successor" and "a great person born of heaven", following in the tradition of his dad and grandfather.
In the North Korean state media, he's portrayed as a young man who can pretty much do it all.
For instance, earlier this year, he reportedly trained fighter pilots and taught the country's military band to play.
Word is, this kind of propaganda goes back to the 1970s, when giant slogans praising North Korea's founder Kim Il-sung and his son Kim Jong-il were carved into a famous mountain.
