Fantastic work ol buddy! I can totally imagine this in the hands of some old scholar. I like the thought of him using it so much that his paper copy wore out. So he spent the extra coin to have a noteworthy cartographer (you) spent hours of painstaking work to reproduce it on goatskin....and still it sees so much use that the edges have become tattered

PS It reminds me of the scene in Game of Thrones where Maester Lewin is reviewing heraldry with Bran Stark.
