These images, which include an alleged alien, were photographed inside a real alien flying saucer, according to sensational claims.
The pictures of a “human-like alien” and “control panel inside a flying saucer” are being published in a new book.
The grainy black and white images appear to show inside a cockpit with seating, control panel and other objects.
There is also what looks like a person wearing sunglasses that is said to be a “real alien visitor”.
According to staggering claims in the book UFO Contacts in Italy, which is about so-called alien contact and abductions in the country, a flying saucer landed in Francavillia, Italy on the Adriatic Coast.
Dr Roberto Pinotii, 73, author of the book, due to be published on February 1, spoke about what is claimed happened.
He said: “Two men were allowed to enter the UFO and take photographs. The diameter of the UFO was 24 metres, that of the control cabin was 10 metres.
“These rare and extraordinary photographs, as well as two photographs of the alleged extraterrestrial pilot.”

The extraordinary events are said to have happened in October 1957.
He added: “Much of the information in this book is being published in English for the very first time.
“The book contains a whole array of UFO/alien contact cases from Italy but surely one of the most unusual incidents is this one from 1957.
“It is the only case that I am aware of that allegedly has photographs of the inside of the UFO.
“What was destined to be called ‘the Friendship case’ started near Pescara between 1956 and 1957.
“A group of local residents seems to have been involved in periodic regular contacts with humanlike extra-terrestrial ‘friends’ willing to help mankind.
“These beings would have built underground bases on Earth and in Italy the most important one would have been in the central zone of the peninsula along the Adriatic coast not far from Pescara.”
It is claimed the “contact” in the area went on for 20 years and even Italian diplomat Consul Alberto Perego witnessed events.
Sceptics say the pictures and the case are just another elaborate hoax.
Publisher Phillip Mantle said: “Roberto Pinotti is an aerospace journalist and author and the main Italian scholar in ufology, with a degree in politics and sociology from the University of Florence.
“He is the only living founder of Italy’s Centro Ufologico Nazionale (CUN), one of the world’s oldest and most authoritative private UFO study organisations formed 50 years ago.”
He was formerly an officer of the NATO Italian Army III Missile Brigade.
He claims to have co-operated with the Italian Intelligence community as a consultant for UFOs and been given important official documents by the Italian Department of Defence.
