The new book is based on sketches and text that Gunilla Bergström worked with before she passed away. Now the book has been completed in collaboration with Gunilla Bergström's son Pål Andersson.
The author was clear that she wanted unpublished material to reach readers, even after her death, according to Pål Andersson.
"The books are the core of everything we do and to let another of Gunilla's Alfons stories spread reading joy in book form is something we are very proud and happy about, as well as something Gunilla herself wished", says son Pål Andersson in a statement.
The first book about Alfons Åberg was published in 1972, and since then 25 more have been added to the classic series. "Julkalas, Alfons Åberg" will be the first since "Skratta lagom, sa pappa Åberg" from 2012.
