The cover of our August issue, which celebrates the historic nature of the upcoming Democratic National Convention, has generated a few predictably lunk-headed responses. One caller argued strenuously -- and apparently with a straight face -- that we should have done a second cover featuring Republican John McCain (remind me again, which night is McCain speaking at the convention?). But the vast majority of the response to our Shepard Fairey-illustrated cover has  been  overwhelmingly  positive . Several callers have even asked for a poster-version of the cover. We're working on something a little more polished and permanent, but in the meantime, we've posted some downloadable versions here . There's also a wallpaper version for the iPhone (you've got your iPhone, right?) So have at 'em. Just like Fairey's original "Hope" poster , you're free to post them wherever you see fit.
