Here's some old wooden threads.
Yeah, I’m not sure how copyright works For republished works. I imagine that if you had an original copy, you could clean it up and sell copies and have a degree of copyright on your cleaned up images. That wouldn’t stop someone else who has an original copy from doing the same thing or even sharing/giving copies away for free. Old books that are out of copyright are often republished, with the publishers claiming copyright, but I thought that would only apply to their facsimile of the original, and not the original itself. I’m only guessing though.I have removed the link although I'm pretty sure the copyright has expired for these illustrations, but that doesn't mean that someone is claiming them. This is a scheme, by the way; print copyright-free images on non-aging paper with lightfast pigment ink and sell them for quite a bit of money. 10 out of 10 points for minimum own effort and maximum profit.
