I have had some info on the cover

The cover will be revealed in the next few days, I think. It’s designed by Emily Langford^{https://www.instagram.com/emdoesbooks/[1]} based on a picture by Tolkien – it’s quite unlike any other cover we’ve done, although we have been at pains to ensure that the spines will match!

Much more obscure is THE BOVADIUM FRAGMENTS, a short tale partly in English and partly in Latin. Here we have Clyde Kilby to blame, at least in part, for the tale's not being better known, in that when Tolkien was thinking against publishing it circa 1966 Kilby advised against it -- a pity, since an anti-car environmental message from Tolkien published in the mid-sixties might have done some good.
