SOLICITATION FOR ARTISTS

Anyone who hast the skill and talent to illustrate in the world's
finest on -line sf magazine should send their color or black-and-white
sample jpg's to ArtDirector@.... Our rates are competitive with
the other magazines. The thing is, you have to be five times better to
get selected. :) —jim baen

Then, find the box called "Baen's Bar" and click it. Join the message
board and then look for the "Baen's Universe Art" threads.

In there you will find someone trying to put together a CGI team to
illustrate the stories. Look for "Join my CGI team" or some such.
