Buy the coasters. Most families have a member who talks about politics, history and current events all the time. From the tone of his (usually) voice, he could do a better job than the president. The coasters are for that guy, in fact, they were made by one of those guys. Buy him the set, and be pleasantly surprised when he sprinkles some facts in with his customary rant.
This website is an adaptation of drawings and text created for a coaster set. Most coaster sets have four to six unique designs. There are eighteen in the Warlords set: one cover piece, one author piece, one map and fifteen warlords. Each warlord has his story on the back and his drawing on the front. The coasters are meant to sit on your coffee table and provoke conversation, maybe even educate your guests a little, but they are also water absorbent and will protect your table.
Buy one set for nine dollars. Sales tax and shipping are included no matter where you live.
Or buy 6 sets for forty-five dollars. Shipping and tax is included.
