A guestbook signed by the Queen, a pair of tartan trousers and a chip fork are to go on display as part of a "living guestbook".
The items have all been donated to the Sheraton Grand in Edinburgh by guests since it opened in 1985.
The hotel is organising the exhibition to celebrate the reopening of the hotel next week.
Each of the items will tell a story from the guests’ stay at the hotel and will go on display in the hotel lobby. The exhibition will constantly change, showcasing all the items which will then be archived online.
It has been curated by Verity Walker who has previously worked for the Imperial War Museum and the National Trust for Scotland.
She said: "Curating this selection of items for the launch of the Living Guest Book has allowed me to get a real understanding of the lifelong memories that hotels create. Over time, the project will expand to create a mappable portrait of the hotel’s guests through their donated items.
"As well as providing a fascinating glimpse into the psychology of an everyday holiday or business trip, the Living Guestbook will give us a greater understanding of how visitors relate to the Sheraton Grand Hotel & Spa, to Edinburgh and to Scotland in general."
The hotel will reopen next week after a multi-million pound renovation.
