Very excited to share this cover from 1930. It is an advertising cover for Charles J. Koehlder in the Hotel Ansonia on Broadway and 73rd. He was apparently a piano dealer representing Bechstein. The letter is addressed to the Bechstein piano factory in Berlin. Love the stamps and the Zeppelin stamp.
Thanks @Parcelpostguy, it is a gem from my collection.
I did NOT know that there was an aluminum piano on board the Graf Zeppelin, or the story about the survival of the piano from the Hindenburg. I'd be very curious to know the brand of the piano! Very cool stuff.
NOTE: The piano was removed before the beginning of the 1937 season and taken to the Blüthner factory, where it was placed on display. The piano was destroyed in 1943 when the factory burned following an air raid during the Second Word War.
I believe the same company mentioned below did the Graf's piano as well.
From the link given by 22crows:
"...the Zeppelin company commissioned the renowned piano making firm of Julius Blüthner to create a lightweight aluminum alloy piano, and the Julius Blüthner Pianofortefabrik created a small grand piano that weighed only 162 kg (356 lbs)."
Serious question, I wonder how hard it was to keep in tune given the high thermal expansion of aluminum and its alloys?
@parcelpostguy Wow! Thanks for the information about Bluthner pianos in the Graf Zeppelins. Really love learning about that and the video of the woman playing the piano is fantastic! We just don't have the same type of travel these days!
One of the treasures in my collection is this 1845 cover addressed to Breitkopf & Härtel. This company is the oldest continuous music publishers in the world and is famous for its editions of Bach and other classical music composers. I have uploaded this before in this thread, but wanted to share my fuller write up and research about the piece - a little bit of info about the company as well as some postal history gleaned from the cover itself. I hope you enjoy!
