Has anyone come across this binding before? It's a 6th impression of the first edition, 1972; jacket not present. I have a 5th impression with the normal dark green binding and the contents are identical. There are no library markings, just this label on the front pastedown.
I've learned old greek and latin for years and also now a bit of modern greek. ΒΙΒΛΙΟΔΕΤΕΊΟ stands for a book bindery so mystery solved, it is only a rebind. As Trotter stated no way it is a original binding with only J. Tolkien on it.
