The photo that helped bring Nazi mass-murderer Adolf Eichmann to justice has been revealed for the first time, alongside the identity of the man who turned him in.
That snap - taken in the early 1950s - shows Eichmann standing to the right of Gerhard Klammer, a German geologist who worked alongside the infamous Nazi at an Argentinian construction firm.
Klammer's involvement in bringing Eichmann to justice was only revealed last week, 32 years after his death, with his family's blessing.
He emigrated to Argentina in the early 1950s to seek work, and began working for the Capri construction company in Tucuman Province, which sits in the north of the country.
Shortly afterwards Eichmann joined the same firm, calling himself Ricardo Klement. Klammer knew of his colleague's true identity, and tried to inform German authorities.

Klammer, pictured as a young man, asked for his role in Eichmann's capture to be kept secret. He died 32 years ago, with his identity finally revealed last week
But they ignored his message, and he never received a response to the astonishing tip.
Klammer shared the identity of his former colleague again in 1959 after returning to his home country.
He confided in a close friend - a priest who had served in the German army, and shared the photo of himself with Eichmann, as well as the mass-murderer's home address in Argentina.
That information was then passed to a bishop, who in turn passed it to Fritz Bauer. Bauer was a German Jewish prosecutor who had made it his mission to hunt Eichmann down.
US troops captured Eichmann after World War II, but he escaped from a prison camp in 1946. He landed in Argentina after living in Germany under a false identity for years, according to Encyclopedia Britannica.
Klammer knew who Eichmann was because their company, which planned hydroelectric power plants, employed many Nazis, according to German magazine Der Spiegel.
Bauer fled his homeland during World War Two, but returned after fighting stopped.
He was the most powerful Jewish prosecutor in the country at the time. Eichmann was widely-known to have escaped to Argentina, but Bauer was the only German lawyer intent on bringing him to justice
Bauer had previously received intel on Eichmann from a half-Jewish man called Lothar Hermann who'd moved from Germany to Argentina.
His daughter had gone on a date with Eichmann's son, who'd boasted of his father's true identity.
That information sparked a 1957 attempt by Israeli intelligence agency Mossad to try and track Eichmann down.
But they couldn't find him, and returned empty handed.
Adolf Eichmann was the 'chief executioner' for the Nazis. He joined the party in 1932 and planned the 'final solution,' which saw Jews gassed or worked to death throughout Europe. He is pictured in April 1961, after being captured by Israeli intelligence officials
