Backdate a picture

I would like to play a prank on one of my friends, and backdate a picture of the soup bowl he has made - so he think that someone else has made that exact soupbowl before 2001. How can I do this - or get in touch with people who can do this?

This is my first post, so I hope i have posted it in the right forum...

Welcome, I don't think it's in the right forum as that's not related to "Blackhat SEO"
