I wanted to contribute to the thread and share a handsome Beethoven collectible from my archive. It's worth seeking out and is terrifically inexpensive when it surfaces.
This is the 80-LP
Beethoven Bicentennial Collection issued by Deutsche Grammophon in 1972.
the companion book from the set is a beautiful leather bound oversize edition with hundreds of pages of the original sheet music, oil painting portraits, and the life story of Beethoven. I picked it up for $2.75 because NO ONE is buying classical lit.
In 2020 I also secured a digital counterpart sourced from the DG compact disc edition of the collection with scans of the accompanying booklets. The audio is v0 as I was unable to acquire it in FLAC at the time.
A nice keepsake for my library.
