Daniel Best has a piece up at his site where Alan Kupperberg explains the awful situation that long-time comic book colorist Tom Ziuko is in, both financially and having to deal with some rough health problems that have prevented him from being able to work (so it's doubly bad - he can't afford his health care and his health is keeping him from being able to afford his health care).
Alan is collecting donations at his PayPal account at firstname.lastname@example.org. In all seriousness, if everyone who reads this just gave Alan a buck, Tom would be a lot better off.
You can click on the above link to see Tom's credits, but suffice it to say that he has colored a LOT of your favorite comics, from 'Mazing Man to A. Bizarro to a long run on Action Comics (before and after John Byrne's run on the book) to Adventures of Superman to Amethyst, Princess of Gemworld to Angel and the Ape to Animaniacs to Arion, Lord of Atlantis to Atari Force to Avengers Classic...this is just the A's, people!!
