The record sleeves state that the proper playing speed for Conqueror Records is 80 rpm.
Conqueror was originally owned by the Plaza Music Company, then became part of the American Record Corporation family of labels. Most of the issues are of standard dance tunes and popular songs of the era, although there is also some jazz, including recordings by Louis Armstrong.
The audio fidelity of Conquerors is about average for the era, pressed into somewhat below average shellac.
