Stephen Hawking's Time Travellers Invitation: Open Edition


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

  • Join Stephen Hawking for his Time Travellers' Reception with the invitation that the Professor hopes "will be around for many thousands of years". Be part of a real time travel experiment with this poster created by artist Peter Dean in collaboration with world-renowned physicist, Stephen Hawking.

    This is an ingenious experiment, devised by Professor Stephen Hawking, to prove whether time travel to the past is possible. By holding a reception for time travellers and not publicising it until after it happened, the professor hopes that future time travellers will one day see it and journey back to attend. The success of this experiment depends entirely on the invitation poster existing in the future for time travellers to find it.

    This stunning screen-printed poster is available in two colours, smoke (grey) and bright citrine (yellow/orange). It has been created from a high resolution scan of a letterpress-printed version, to maintain the same Victorian style and steampunk feel as the limited edition prints proudly displayed in Stephen Hawking’s home and office.

    As seen on TV! This print featured on The Late Show with Stephen Colbert.

As seen on TV! Our Time Travellers Invitation Poster features on The Late Show with Stephen Colbert

It was a great surprise for us to discover that one of our Stephen Hawking Time Travellers invitation prints was seen on The Late Show with Stephen Colbert.

It featured during an interview with Swedish actor Alexander Skarsgård (who plays Tarzan in the 2016 movie) who apparently once snuck into the Ed Sullivan Theater in New York pretending to be a roadie – and had his photo taken with Colbert. Our print is up on the wall there and crept into this shot. The citrine colour steals the limelight nicely!
