See this online exhibition at the Boston Public Library:
On the Edge – the Hidden Art of Fore-Edge Book Painting
This website highlights a special collection of more than 200 high-resolution images of fore-edge paintings housed in the Rare Books Department of the Boston Public Library. Includes articles on the history of fore-edge painting by Anne Bromer and Martin Frost, and an essay on the BPL collection by Muriel Figenbaum.

What an interesting little sidebar in literary history – thanks so much for the link!
If you are in Boston this collection is well worth a visit.

Hello Martin, I have just looked at your website and very happy to know about you and your work! [I will add a link to the main post as well] – I expect to be in Boston next week and will hopefully visit the Library – I see that some of you work is there as well.
Thank you for visiting and sharing!
