Doctor Who is a world-wide phenomenon that has spanned decades. It is produced by the BBC and is the longest running sci-fi program ever. The story centers around a Time Lord, the last of his kind who can move between time and space. He travels in a ship that on the outside looks like an English police box. The joke is when the door is opened to this tiny looking box there is a huge ship on the inside. It is called the Tardis. Time and Relative Dimension in Space. He loves the earth and works very hard to protect us from forces beyond our comprehension. This royal blue, 100% cotton t-shirt is officially licensed from the BBC. If you're a fan you should have already bought this shirt. So now is your time.
