This appears to be a demo record to sell a song and/or performer.
Although not marked on the record, I would guess by sound quality about 1960.
Based on the high frequency response, I would guess RIAA equalization was used.
I used no noise reduction since the quality was so good.

Before tape was popular, recordings were made on Acetate Discs. These were an aluminum disc coated with Acetate which can be recorded
with a record cutter stylus. The blanks had an extra 3 holes to provide traction since the stylus would develop significant drag.
I purchased many of these discs in the late 1960s early 1970s from Salvation Army. It was easy to spot these in stacks of 78 RPM disks
because the edge was shinier. Many came from radio stations.
