The history of Montblanc in Denmark

My family just gave me this book for my birthday. It’s a well-told history of Alfred th. Øberg and Montblanc pens in Denmark.

There is also a little information on Christian Olsen (Penol, Skribent) and Neils Benzon (Big Ben, Benco, Wahl-Eversharp) and the inter-relationship of the three companies.
