A letter written by Oskar Schindler, the German industrialist who saved some 1,200 Jews from the Nazis, to his bookkeeper Itzhak Stern is for sale online.

The letter is on sale for $32,500 on the website MomentsinTime.com, which deals in rare original autographs and historical documents. It was put up for sale by a descendant of Stern, who composed the list of Jews that Schindler saved by calling them essential to the running of his factory, Page Six reported.

The two-page letter, which is type-written in German and can be viewed on the website where it is a featured item, is from 1963, and deals with the industrialists’ finances.

“If I think in retrospect, that a year ago I was with you and full of optimism towards the future, and now/today I have to carry the effects of the last year, I sometimes ask myself if it’s even worth living,” Schindler writes in the letter which discusses the “desperate situation” of his finances.

Schindler attempted to start several businesses after World War II, all of which failed, leaving him bankrupt.
