This item is a Magic the Gathering playmat featuring reimagined artwork of the Library of Alexandria by artist Mark Poole originally featured in Arabian Nights. The artist named the piece Library Nocturna.
The playmat is embroidered, i.e. it has been stitched with thread on the borders to improve durability and to make it even more visually stunning.
This MTG playmat has been signed by Mark Poole and is, thus, very rare.
The playmat size is around 35cm x 60cm.
