Created by Peter Dean with the approval of world-renowned physicist Stephen Hawking, this poster is part of a real time-travel experiment.

Professor Hawking devised an ingeniously simple experiment to prove whether time travel to the past was possible. He held a reception for time travelers, but didn’t publicize it until after it had happened. This way, only those who could travel back in time would be able to attend. The success of this experiment depends entirely on the invitation poster being seen by time travelers.

It is a 16″ x 20″ Letterpress print available on black or white paper, each editions of 100 and cost £140 and £140 respectively. Open edition Screenprint versions are available as well. On sale now HERE.

“I’m hoping copies of it in one form or another will survive for many thousands of years. Maybe one day someone living in the future will find the information and use a wormhole time machine to come back to my party, proving that time travel will, one day, be possible.” – Stephen Hawking
