Steven Hawking came up with a simple and clever way of seeing if time travel is possible. On June 28, 2009, he threw a party for time travellers from the future...but didn't advertise it until after the party was already over.
In an effort to improve the chances of the party invite being noticed by future generations, Peter Dean, working with approval from Hawking, has made this gorgeous hand-printed poster of the party invitation:
There's also a smaller less-expensive version of the poster in grey and a fetching yellow/orange.
Peter Dean is a big Beatles fan. And so he set out to reproduce exactly -- from photographic evidence only -- an old circus poster owned by John Lennon. In true Sgt. Pepper's fashion, he had a little help from his friends.
This is a reproduction of the poster that inspired John Lennon to write the song Being for the Benefit of Mr. Kite!, which appeared on The Beatles' 1967 album Sgt. Pepper's Lonely Hearts Club Band. It is printed in a limited edition of 1,967.
Lennon bought the poster in an antiques shop and hung it in his music room. While writing for Sgt. Pepper one day, he drew inspiration from the quirky, old-fashioned language and set the words to music.
A limited edition letterpress reproduction of the poster is available for sale.
