Hello, the book Elvis i Danmark has the a miss-spelling in the author name, and in reality belongs to Bertel Nygaard. The author listed right now "Bertil Nygaard" doesn't exist. I've searched the publishers website, and the Danish Libraries.
Here's some additional informaiton from the publisher: Alternative title: Elvis i Danmark - 65 års populærkultur 1. Edition Hardcover ISBN: 9788712062691 Page count: 266 Publication date: November 6th 2020
My information is from the publishers website, which also include a cover photo:
