Madame Tussauds revealed their books as Buckingham Palace unveiled an online book of condolences on the Royal website.
The waxwork museums released a statement to inform tourists as to how they can pay respects and share memories about Her Majesty.
The London Madame Tussauds, located near Baker Street, said: “We join millions of mourners around the UK and the world in paying tribute to Her Majesty Queen Elizabeth II.
“A special condolence book has been placed alongside Her Majesty’s figure to allow guests to record their thoughts and tributes.”
They added: “United in our loss - we give thanks for an extraordinary service to this country, the Commonwealth and the wider world.”
The London museum stated that it would remain open until the day of the state funeral (Monday, 19 September) when it would close for the period of national mourning.
However, it has applied some changes to their exhibitions to show “some respect and sensitivity.”
The Blackpool Madame Tussauds spoke about their book of condolence which is put next to the Queen’s statue and her beloved corgis.
The institution said: “During her life and 70 year reign we have created over 20 different figures of The Queen to mark different moments in her iconic public life.
“Madame Tussauds has a long-standing relationship with The Royal Family and worked closely with the Palace on the creation of these figures.”
Madame Tussauds held sittings with HM The Queen from 1928 until 2001 and has created 23 waxworks of the monarch over her 70-year reign.
The first statuette was created when Queen Elizabeth II, then Princess Elizabeth, was just two-years-old.
According to the museum’s website, the waxwork sculpture was made with a team of 25 artists and took a total of 800 hours to complete.
Madame Tussauds will be closed for the Queen’s funeral but will reopen the following day on 20 September.
