300 pixels/inch is standard print size, so I'd go with that and downsize it to whatever at the end. As for me, I'm working on something that happens to be around that size, but it probably won't be done until around next weekend. It'd be cool if you could push the due date to around that time, but if you get enough entrants willing to have it by this Monday then you can leave me out since my piece isn't specifically for this.

We can do bands that don't exist, correct?
