Stephen Hawking's Time Travellers Invitation - Kite

Stephen Hawking's Time Travellers Invitation

Professor Stephen Hawking devised an ingeniously simple experiment to determine whether time travel into the past was possible. The success of the experiment depends on his invitation being seen by time travellers. With Professor Hawking's approval, we have created a version of his poster printed in two letterpress limited editions and an open edition.
