I'm not a calendar collector, but I ordered some books from Ebay a while back and included was an interesting item. It's a 2005 50th Anniversary Calendar signed by Priscilla Tolkien. It's inscribed: "For Pieter Willem With best wishes from Priscilla Tolkien" and includes a letter from Jan-Stefan van der Walt to the recipient (the calendar was a wedding gift apparently). It seems from what I've found online that the van der Walt family maintained Tolkien's father's grave in South Africa and assisted the Tolkien family in celebrating Tolkien's 100th birthday in Bloemfontein.

The condition is very good - there a few slight bends and a few light scuffs on the back. I have no particular attachment to the item and am interested in selling it. Any thoughts on value?
