We all know artists who like to collaborate, who like to work as a team. It all kind of depends what your habitual working method is.

The poster art over the years, art with social critique in it, has always been on class war theme. It's been trying to make that point - that we are larger than they are. They may have guns and pepper spray and helicopters and F16s and the whole U.S. military on their side, but when it comes down to it, we still have the numbers.

In the U.S., ironically, people work longer hours in the U.S. than they do in Europe or in any other industrialized country. They seem utterly oblivious to May Day, don't really know what it is - our own history.

The unusual thing about doing street poster art - or something with a conscious social critique in it - is that the artist thinks they're a little in control, focusing and trying to make a specific point. But even then, when you look at it a few years later, you realize you were just working through some of the usual feelings you were going through during that time.

Having your work in a museum is something we as artists aspire to, but I don't think that's something we need to worry about while we're alive.

Whether it's a street poster on a brick wall, a magazine cover on a newsstand, or animation on a movie screen - art is an effective means of communicating with large numbers of people.

Let me see: art and activism. I can always fall back on, "the question should be, what isn't political? Everything you do is political, even if it's abstract. You're making a political statement even if it's unwittingly." I think so much of art is unconscious anyway, the artist doesn't know the real reason they're doing it. They're just kind of going along with it intuitively.
