Mont Blanc pays tribute to one of the great masters of the Baroque period of music with its limited edition pen dedicated to Johann Sebastian Bach. Composer of the "Brandenburg Concertos," "Air on the G String" and many secular and religious pieces, Bach was most noted in his time for his work on the organ. It appears never to have been used. The piston is clean of any ink, as it smoothly goes up and down the barrel with a twist of the still stickered blind cap. The gold-plated cap ring features a portion of the "5th Brandenburg Concerto." Click headline for pic of nib.
