Charlie Murphy Graciously Takes Pic with Fan Weeks Before Death

Charlie Murphy was gracious to the end ... taking time for a fan weeks before his death.

Michael says Charlie was super nice.

Turns out Charlie was in and out of the hospital, undergoing chemo but kept his illness secret to almost everyone.
