All Men Must Serve Mug - The Caveman's Guide

Keep Winter at bay with a hot beverage of your choice, served in this super-stylish Game of Thrones Mug. 

When it's cold the mug will display the message 'All men must serve//Valar Dohaeris'. Just add (hot) water and watch the picture change, as George R.R. Martin's universe comes to life with a map of Westeros.
