I bet if you ask the librarian (head for that particular branch) if you could have it (or buy it from them, if they have a Friends of the Library local support group) when they are ready to swap it out, they would go for it - assuming it’s in good shape, of course.
I know what you mean, and they make those regularly for libraries so I assume it’s possible, but you can also always take a good quality file and go to say a Fed Ex Office and output it yourself on good quality paper via a color copier. That will only get you an 11x17 version, but still.
That’s a nice piece. I wish Derington would do some interiors again, it’s been a few years since he has.
