You could get your hands on £1m pounds if you take a photograph of the Loch Ness Monster!
The prize has been offered by organisers of a rock concert which is being held at Inverness in Scotland, near to the Loch Ness stretch of water.
Some people believe the Monster lives deep in the water. But it must be shy as not many people have 'seen' it!
Organisers of the Rock Ness gig will be providing 50,000 cameras in case someone spots the mysterious animal.
Prizes will be offered for the best evidence. They can be real or made up, like the picture we have used above in this story.
So, if you happen to be in north Scotland and see a dinosaur-like creature popping its head out of the water, take a pic.
It could make you very rich!
