Map rendering by myself, with Thangorodrim, compass rose and tengwar frame by Kuba Tymiński 'Ominous'. Published on-line with his permission. Done in Painter and Photoshop. 
Based on on maps by J.R.R. Tolkien in HoME vol. XI, Christopher Tolkien in "The Silmarillion" & Karen Wynn Fonstad in "The Atlas of Middle-earth", and information from Ominous who has browsed texts for additional information and places to be added to the map.
