Could you give me a hint?

Hello, my friend. You're incredibly lucky that I'm interested in your topic. Because I work in publishing and your question is my area of expertise. In fact, there are a lot of similar photos on the Internet, but few of them are of high quality. And if you look in the large format printing folder, you will see exactly what you need! No need to thank me!

I also worked at a publishing house as an operator of these huge printing machines. I can tell you that the job was very difficult, but highly paid. I liked it until we started working evening shifts.
