Old Tolkien calendars.
As in, the 1974 Tolkien calendar, the first (I think) with Tolkien's own art.
As in the 1975 Tim Kirk calendar, which I don't think I've ever even actually seen before -- I've seen the art, or most of it anyway, but don't recall seeing the calendar itself.
Add to that the Hildebrant calendars from 1976, 1977, and 1978 (one or two of which I have, or at least had at one point -- not sure if they survived the house or not). The Bakshi calendar of 1979 with the movie art. The 1980 'Great Illustrators' calendar, with its hilariously, famously bad picture of the death of Boromir based in equal parts on images of St. Sebastien and the Pieta.
Living down in Arkansas as I did, I don't think I had the chance to buy a Tolkien calendar for myself until I discovered Land of Legend, the Zaentz marketing company for items centered on the movie (like the Lord of the Nazgul piggy bank), along with a few other interesting items -- such as Tolkien calendars, Anne Etkins' little book, et al.*
So now I'm going to get out all my old calendars that have survived time, decay, and many many moves, and introduce them to their new friends. And find a new home for them all, in the box room.
