If you haven't watched the HBO series Game of Thrones, I highly recommend you find a way to do so.
Here's a description from HBO's website and the link to buy them.
Add the Game of Thrones Distressed House Sigil Pint Glasses to your collection for a shake-up in traditional bar ware. The sigil graphics are roughed up to give them an aged look. The illustrations, as always are outstanding, giving the Game of Thrones Distressed House Pint Glass Set an unexpected quality. The opposite sides of each glass bears the House pledge.
