Description

Vintage J.R.R. Tolkien Calendar Lord of the Rings lot of 5 (75,77,79,80,81) Rare.
Really great condition all around.  No markings that I could find on the inside.  Some minor dents and dings on some.  Some have nail holes show that these have been hung before.  What looks to be scratches from being slid over the top of each other.  All scratches seem superficial and to not have gone through the print.
1975 small tear and smash on right side (pictured).  This looks to have caused a small wrinkle about an inch in where the print has peeled in the crack but doesn't go through.  Two small crease points on top.
1979 is in really good condition and does not seem to have been hung before.
1977 has a very small tear (1/8th of an inch) on the bottom left.  Small corner scuff top left and a bit on the side (whitening).
1981 has a little side wear around the bottom right side.  Small crease damage across the top in a few spot.  Looks to have been hung.  Small indentation by nail hole.
1980 small crease damage across the top in a few spots.  Bottom left corner on the back is torn off (cut maybe?) and is barely hanging on.  About a 1/2 inch base and height of triangle shape.  Looks like it was hung by a nail but is slight.
All questions welcome!
Thanks for looking!
