President Obama gives British PM Gordon Brown 25 DVDs. Gordon Brown is going blind and British DVD players do not play American region 1 DVDs. Also the British PM gave the American POTUS unique items/artifacts, and the American President gave non-unique stuff.
The President of the United States gives the Queen of England an iPod filled with his speeches. She gave him the standard plaque for foreign dignitaries. So his gift to her was more unique, yet disgustingly narcissistic.
