I've also recently done some work on a poster, again for a friend. She sent it away to be framed, and when it came back from the shop it had been nastily creased, to the extent that it had white bits showing through the printing:

I flattened the creases out, touched up the white bits with watercolours (I'm particularly pleased with the colour match on the skin and hair, which was a sod!) and then mounted it again, properly this time:

I've just finished repairing a friend's copy of Mother Goose’s Nursery Rhymes, Tales and Jingles, with 400 illustrations for her.
It's, I think, the 1890 edition (some of the first section, including presumably the page with the printing date, is missing), and it was published by Frederick Warne & Co.
I originally thought it was a simple "stick the boards back on" job, then I saw photos and realised that it would probably need to be re-sewn, then I actually got my hands on it and realised that about a quarter of the sheets needed the folds repairing, but hey ho: it was quite fun to work on, and it only took a couple of days!

(If you look closely at the sewing, you can probably see that the thread doesn't go into every section at every sewing station: it's sewn two-along, which is a way of saving time but is part of the reason it's fallen apart after a mere hundred years or so.)
After I went through and repaired the folds, the text block was ready for re-sewing:

And then I stuck the covers back on:
