Two record sets had been distinguished by the “Black” and “White”
First annual PLAYBOY JAZZ POLL was held in 1957.
The result of the vote had been sold in the black cover design.
The results of next year had been sold in the white cover design.
Below,I transcribe the preface of liner notes.
”All the cats joined in to make the first annual PlAYBOY JAZZ Poll the biggest,most successful popularity poll ever conducted in the field of jazz music.
