78 rpm SP record. It's Telefunken E2590/4 from Germany (12-inch, set of 5). Completely original pressing. The record surfaces are like new, gleaming. In excellent condition. The recording is Beethoven's "String Quartet No. 14 in C-sharp minor, Op. 131". Performed by the Calvet Quartet. Recorded in Berlin on January 19, 1938. A masterpiece that needs no explanation. Gigantic rare record.
