On the cover of the book, comedian and author Aron Flam has paraphrased the image "A Swedish tiger". The original image was used in a classic advertising campaign during World War II and it is copyrighted.

In Flam's version of the picture, the tiger is modified with a swastika around one leg and another leg lifted in a National Socialist greeting. Aron Flam believes that the cover is a satire, but the Emergency Management Museum, which owns the rights to the original image, reported Flam to the police for copyright infringement.

"A restoration"

The book has been seized since June, but now the seizure has been lifted.

- It is a restoration for Aron Flam and a strict reprimand to the prosecutor, says lawyer Monique Wadsted who represents Aron Flam and Samizdat Publishing, the publisher who publishes the book, in a statement.

She assumes that the decision will lead to the prosecution now being dropped.

- Sweden is not a country where the state must seize books and bring satirists and debaters to justice, she says.

The Emergency Preparedness Museum declines to comment on the incident.
