I recently discovered polish editions of the first two Jonathan Intégrales, published by Wydawnictwo Ongrys. The albums were translated by Daniel Pánski.
There is an interesting story behind these polish Jonathans. In 2020, publisher Ongrys asked readers which comics they would like to read in polish. Jonathan ended on de sixth position in the ranking, but was one of the first series to be translated. One of the reasons behind this decision was that the Intégrale albums were available, so the polish publisher could start with a decent body of work.
In June 2021, the first album was published, the second album in December 2022. I hope the sales figures will meet the expectations of the publisher.
