You have carried out some shady work and need paying. The scheme is that you are given a piece of canvas with a line on it. You need to keep hold of it for a period then you will be told which auction to take it to. Two phone bidders will talk up the price to $20 million and you will be paid with suitably laundered money. The bidders can remain anonymous, of course.
A different idea that I heard about some time ago is that the criminal mastermind also owns a casino so all shady work is paid in casino chips. You take them to the casino, have a sall dabble and then cash in your chips. Again, money is suitably laundered.
