Beethoven, Eugen Jochum, London Symphony Orchestra - "Eroica" Symphony No. 3 In E Flat / Overture To Egmont (NOS) (New Vinyl LP)

This is NOS still sealed from the late 70s (see pics). I have never seen this before, but this 2 different releases packaged together. Came from a music reviewer of a classical music magazine during the 50s-70s. Said he never opened it.
