Sir Elton said: "The John Lewis Christmas campaign has so many warm memories for me and my family". The space includes dressing room, recording studio and living room sets from the ad, as well as props, recordings from Elton John's 17-11-70 album and the opportunity to have photos taken at the piano.
Earlier this year, a source told a United Kingdom newspaper that "John Lewis wanted to win the battle of the Christmas adverts this year, and it has cost them a significant sum to do it".
The reaction to the ad have been mixed.

As the familiar dulcet sounds of "you can tell everybody, this is your song" play, you watch the reverse trajectory of Elton John's musical career, beginning in present day.
The move comes ahead of John Lewis' much-anticipated Christmas campaign, which is reported to contain a starring role for the musician.
Speaking to Marketing Week, Inglis explains: "What we've found over the past 10 years is that this kind of advertising, which connects with people on an emotional level, is what really is most powerful at Christmas".
It wasn't universally loved, with some complaining the advert was selling John's life, more than it was Christmas.
Having reportedly donated his £5 million fee to his charity, the Elton John Charitable Trust, Elton's husband David Furnish admitted that making the ad was an emotional experience for the star.
