In my vague knowledge of early printing presses, the style of pressing is a little different depending on the model of printer. I figured Otto might be able to recognize the quality of work or the type of press used. Maybe Ink and paper would provide a clue if it was done crudely, in an early movable type, a roller print wheel, etc.
Basically, maybe Otto can give some advice on where it came from. Or at least recognize work from his own shop. Which maybe it is...
Or maybe he is an HP Inkjet Printer with a wifi connection.
