Not really sure, but he ends up tied up (along with your character) later on in the Black Widow's lair.

under the palm tree hope you complete it!
At the end of the tunnel.
you scoot over to the shady guy and he will undo them for you
When he leaves he will leave it on the docks
the jazz place
Search it on google then when you find it, print it out?! Everyone knows that!
There are no sharp tools on Counterfeit Island. The balloons are popped by clicking them, and you free yourself from the chair by "scooting" it backward to the shady guy who is also tied up.
It arrives at the museum after the Shady Guy escapes in the scooter chase. (When you are released from jail, you get the timecard from the security guard at the Clown Store, and look at the videos in the museum Security Room. The mimes will point you to the All That Jazz Club.)
The shady guy on Counterfeit Island gets caught by the police and arrested for his criminal activities, specifically counterfeiting art. He is then taken away to face justice for his crimes.
One piece is on the beach at the Docks, near where you meet the shady guy at the Tunnel Tour exit.
The shady guy meets you at the Docks exit from the Underground Tour, and tells you to enter the museum to stop the theft.
