Each celebrity's card is being auctioned on eBay from Dec. 10 to Dec. 23, with all proceeds benefiting The Lustgarten Foundation for Pancreatic Cancer Research. The key search words to log onto eBay are "cards for charity."
Among the celebrities who have created their own holiday cards are: Jessica Simpson, Julianne Moore, Jay Z, Donald Trump, Woody Allen, John Malkovich, Ja Rule, Kelly Ripa, Ashanti, Glenn Close, Adam Sandler, LL Cool J, Derek Jeter, Howard Stern, Kevin Bacon and Bill Cosby.
"I was happy to take part in this great project with all these other really cool people -- Adam Sandler, Chris Rock, Derek Jeter and more," said Jay Z. "Hopefully we'll help raise a lot of money to combat this terrible disease."
