This is the very first vinyl LP printed for the (soon to be announced) "12 inch LP's" for the Columbia catalog, and is considered the first (modern) 12 inch LP ever.
This LP also coincides with the 1st 10" LP The Voice Of Frank Sinatra
that Columbia Records unveiled at a press conference in the Waldorf Astoria in June 1948.
Notes from rear jacket: This Columbia Long Playing LP Record is a modern high quality musical reproduction worthy of your special care: Always keep it away from heat and in the protective envelope.
Different label layout here: Mendelssohn: Concerto In E Minor For Violin And Orchestra Op. 64
