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 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, he hoped that future time travellers would 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 was created from the letterpress-printed version we created — proudly displayed in Stephen Hawking’s home and office – which is now part of the permanent collection of the UK's prestigious Science Museum.

    With permission of the Estate of Stephen Hawking. And 10% of the purchase price of every print sold goes to the Stephen Hawking Foundation.

  • Please select one of the 'Framed' options above.

    Prints are framed professionally, to order, by a Guild Commended Framer using archival-quality materials and usually ship within 7 working days.

    Frames are wooden with a black finish and are sealed on the back to prevent dust from entering. D-ring attachments and hanging cord are also fitted, so the print will arrive ready to hang. A card is also attached to the rear of the frame containing information about the print and Professor Hawking's experiment.

    High-quality, optically-clear acrylic is used in place of glass for all shipped orders. It is visibly identical and should not be cleaned or polished with abrasives.

    We package framed prints carefully to protect them from damage during shipping.

    The overall dimensions of the non-mount/mat frame are: Width = 390mm, Height = 496mm, Depth = 23mm. The frame itself is 23mm wide all around.

    The overall dimensions of the frame with mount/mat are: Width = 440mm, Height = 582mm, Depth = 23mm. The frame itself is 23mm wide all around.

  • We take great care with packaging to help ensure that your print reaches you in excellent condition. Prints are wrapped in acid-free tissue paper and shipped in large-diameter, thick-walled tubes with secured end caps.

    We ship worldwide, and regularly send orders to the US, Canada and Australia. Depending on the destination, orders for multiple prints may arrive in multiple packages.

    UK orders are usually delivered within two working days after dispatch. International orders are normally delivered within 5–10 working days after dispatch.

    Customers in the EU may have to pay a small amount of import duty to receive packages sent from the UK.



"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

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!
