Shortly after receiving approval to create our Time Travellers Invitation print from Professor Hawking himself, we had the privilege to meet him and present him with his own copy. He liked it so much that he requested a second copy to hang up on the wall of his office at the Department of Applied Mathematics and Theoretical Physics at Cambridge University.
One thing that's abundant in Professor Hawking's office is the sheer volume of pictures on the walls. There are photos of him with the Pope, with Obama, and dozens of other luminaries stretching back decades. So for him to find a spot for our work too makes us very proud.
The poster itself is at the centre of an ingeniously simple time travel experiment devised by the Professor, and one that you can be a part of just by displaying one of our prints.
If you'd like to find out more about the experiment and have a copy to put on your own wall, then check out the print here:
