The cover art for Mastodon's most recent release, The Hunter is pretty phenomenal. Whatever that thing is, it's cool, and this new piece of merch from the band continues it's coolness. The Atlanta quartet is selling these limited edition masks in their webstore, that were handmade in LA by a makeup effects company. Each mask is numbered and will set you back 40 bucks. Who wants to get Rob an early gift for the holidays?
