(JTA) — A New Hampshire company is auctioning off a set of documents related to Oskar Schindler.

RR Auction company, which specializes in historic documents, has made the items available for bidding until Aug. 14. Prospective buyers can big on the documents on the company’s website.

Among the documents up for sale a letter Schindler wrote asking for permission to move his factory from Poland to the city of Bunnlitz, in Czechoslovakia, according to Fox News. The relocation allowed Schindler to save his Jewish employees from certain death in Nazi concentration camps.

Also for sale are detailed blueprints of Schindler’s factory, including the living quarters of over 1,000 Jewish workers saved by Schindler during World War II.

Recently, a typewritten copy of Schindler’s list of 801 employees failed to sell on the auction site eBay.
