Tumba Bruk was the printing company responsible for the manufacturing of the Swedish krona banknotes.
The company was founded by Sveriges Riksbank in 1755 to produce banknotes, making it the world's oldest factory of its kind.
In 2002, the company was sold to the current owner, banknote paper supplier Crane & Co.[1] It is located in Tumba, close to Stockholm.
These notes soon became worthless, however, when Stockholm Banco went bankrupt in 1668, and banknotes were subsequently prohibited.
Banknotes received a second chance in 1701 when the predecessor to Sveriges Riksbank started handing out transportsedlar, notes that worked in a similar way to modern cheques.
