In 2014 (I think) Montblanc released two pens in the 149 format connected to the Teatro Alla Scala opera house in Milan. One was a metal pen with black lacquered portions and inset diamonds with an engraving of Salieri on the nib as it was his opera 'Europa' that was the first performance in 1778. The other was a normal 149 with the engraved garland and imagery of the balcony tier swathes on the cap. Both were of a limited number. It wasn't an anniversary (so long as my pen release date is correct) so I was simply wondering if this was meant to be a series on world or European opera houses that was abandoned? Or was there another reason for this release?
