Hey now. I need to see a little more sympathy for the Yankees, and I'm saying this as a die-hard fan who has never been to a game or bought merchandise and who recently had to ask a friend "Which is the one that never wins the World Series? That's a baseball thing, right?"
...But my sister says that we are Yankees fans, and I believe her. Truth is I love this cover just because it sums up the New England life so perfectly. No corner of our six little states is safe from the battle of these two teams, and while it does vary with location (I moved twenty minutes closer to NYC and suddenly it's Sox everywhere), you still always have your representatives of both sides. I'm sure that most other lands have their token rival teams too, but I wouldn't have recognized any other pair.
I don't know how widely this cover will be distributed. I picked up the link for Whedonesque from the artist's Twitter, and this is all she said on it. I'm still looking for more info on the New England tour, because I really want to be there.
Oh, and as I explained elsewhere, Angel's wearing those team colors because Faith made him. Not wanting to fight, he acquiesced for this one night, and by lucky coincidence they found a Yank vampire to take down, and Angel, who had never cared about baseball before, suddenly discovered how much fun it was to defeat an enemy while crushing his team spirit at the same time.
