I've been fortunate enough to chat at length with a couple of these artists at RPG-related conventions, and I thought the book treats professional visual artists with well-deserved respect.
While it unfortunately doesn't cover every single artist to have ever had illustrations in a Mage rulebook, it does cover more artists than I was expecting. The text doesn't drop any lurid gossip, and it has the length and tone of informative art museum entries as you walk from exhibit to exhibit.
(and I don't mean to poke fun, but considering how many artists artistically place their own hard-to-decipher initials in their work, it IS nice to finally see their names clearly-spelled, front-and-center, surrounded by instant visual reminders of, "Oooo! I didn't know she did THAT one too!")
