Two greetings cards sent by Princess Diana to the King of Greece - which featured cheeky sexual innuendos - are up for sale at auction.
The artefacts show Diana, Princess of Wales' funny side as they include handwritten messages and her signature.
The first card had a cartoon of a naked man leaning on a tree with the caption "Adam came first...Men always do!..."
The second showed a naked woman with the message 'What's the definition of the Perfect Man?' followed by the answer: 'A midget with a 10" tongue who can breathe through his ears!'
Diana sent the cards to Constantine II, the last king of Greece, who reigned for nearly ten years.
Both cards are up for sale at Dominic Winter Auctioneers auction house where they are expected to sell for up to £5,000.
Both cards were signed by the royal with one reading: "Dearest Tino, lots of love from Diana". The other said: "Dearest Tino, proudest love as always, from Diana".
The cards are going up for auction on Wednesday May 17 at 10am.
The cards are listed on the auctioneer's website with the following message: "The reason for sending these cards, other than as a bit of fun, is unclear as the cards do not celebrate a birthday, Christmas or christening.
"Diana must have seen these cards and thought of Tino before buying and sending them, possibly inspired by a conversation they had had at some social gathering."
Both Prince Philip and Princess Diana were godparents to Prince Philippos of Greece and Denmark, the youngest son of Constantine and Anne-Marie of Denmark.
