Picked up a book on German phone booth ad-art and got fascinated with the old-school grainy xerox style again, a mother of necessity, which is where I started. Used to blow out 35mm contact prints to get this kind of quality. Nowadays it's just a Photoshop plug-in away. You got serious issues if you're calling up a 1-900 number, talking to some old granny, and you're thinking you've got this gal with the super-bullets on the line...
