It is a rare glimpse into the childhood of Nazi Germany's second most powerful man.Heinrich Himmler was one of Hitler's closest confidantes and also the architect of the Holocaust, in which he coordinated the killing of six million Jews.
Yet this extraordinary image reveals a bit of the monster's life as an 11-year-old boy before he went on to commit atrocious war crimes.
With his mother a devoted Catholic, she not doubt wanted her young son to follow in her footsteps.
And this rare printed communion certificate shows that Himmler was received into theRoman Catholic Church in 1911.
It will be sold alongside a number of other fascinating items which belonged to an American woman whose father, Lieutenant Richard J Wills, was tasked with remodelling Himmler's home in the Alps into a senior officers' club after the Second World War.
One of the rarest items which will be sold at Mullock's auction house in Shropshire is a postcard from Hitler wishing Himmler's mother a happy 75th birthday.
Dated 25.IV.27, the letter is regarded as being 'excessively rare'.
Other lots in the auction show photographic and oil portraits of Himmler in his SS uniform.
Himmler was born in 1905 in Munich to a middle-class family.
He began training as an officer during the First World War but the conflict had ended before he could be sent to the front.
He went on to study agriculture and for a short while was a chicken farmer.
He joined Hitler's fledgling Nazi party and soon became a trusted aide and even towards the end of the war the German leader referred to him as 'der treue Heinrich' (the loyal Heinrich).
However, In 1945 a disillusioned Himmler believed victory had slipped from Germany's grasp.
He secretly attempted to start peace negotiations with Eisenhower, who was then Supreme Commander of the Allied forces in Europe, in a bid to escape a war crimes trial.
But Eisenhower refused to have anything to do with Himmler.
A furious Hitler declared Himmler a traitor, stripped him of his powers and the SS chief went on the run.
When Himmler was arrested by the British at Bremervoerde on May 22, 1945, he had disguised himself by shaving off his moustache, wearing an eye patch over his left eye and he was carrying false identity papers.
However before he could be interrogated, he committed suicide the following day by swallowing a cyanide capsule.
The total lot is expected to fetch £40,000.
