I have seen this picture before on a site but sadly I forgot the adress.
On the picture you can see the races of middlearth; hobbits, elves, men (you get the idea
)
They stand on a row all strictly lined up facing forward. At the left side of the picture there is a kind of measuring stick, which ables you to see the height of the races. For example you can find out that the average height of men in middlearth is 5"10. I should also mention that the picture is made in black and white.
If anyone has seen this picture please post it or give me a link. I would be most grateful if i could get my hands on it!
