Only once before has the Phactor gotten the cover picture for a scientific journal where the cover illustration relates or is taken from one of the articles in that volume. But the 2nd cover picture is on its way according to the journal's editor by way of asking for some text describing the image. No question about it, you have to buy five copies for your mother, although these days it'll just be a pdf file. In the grand scheme of things, this counts for very little; it's just kind of fun. Still you have to have at least 5 cover photos before you can even be considered for the centerfold!
