Next door to the Hamburg factory where luxury-goods manufacturer Montblanc produces its fountain pens and other writing instruments, you’ll find an “autograph library.”
There, enshrouded in glass as part of a permanent exhibition in what is known as Montblanc Haus, are the signatures of authors, artists, musicians, and other notable people – some known for using Montblanc pens, others not.
