This item is a Magic the Gathering playmat, from the Has Con 2017, featuring artwork of Grimlock, Dinobot Leader / Grimlock, Ferocious King by artist Tyler Jacobson originally created for that event.
This playmat is double-sided, meaning there is artwork on both sides of it, just like in the card it represents. You'll never get bored of it.
The playmat size is around 35cm x 60cm.
