Actually, what the guy framed was a row of five prints; he was just thinking of a one-off to exhibit for fun at the time. But his printer would do it as one piece. If anyone ever actually bites for this, what they will get will be on Epson premium photo paper. No, not simulated master painting with brush strokes; but I betcha the poster shop doesn't put near the time and effort into doing one of those that putting one of these together took. :)
Then again, I could pick up some printer canvas, hit the brush-stroke filter button in photoshop, and let anybody have it that way for the price; but I hadn't thought of that style being really relevant to this kinda goof-off "art".
