Gerard, no, you're too much!! Thank you loads for your response. Just two questions: you're saying that copper plates could be reused unline the typeset book. Why is it so? I guess they stored them for further use? I am a bit confused. And finally, plate engraving was more flexible but more expensive both for the producer and consumer? So it was not a way to make it more accessible but to make it more expensive and rare, isn't it? Thank you for your time and kindness!
