Edison-Bell Records was an early label on 78s, eg. see "A Sunday Parade"
But is the name of the label "Edison-Bell Records", or is it "Winner" as printed on the label, or as it is shown here: "The Winner Records"?
Or is Winner an imprint of Edison-Bell Records?
Both are labels.
According to Wikipedia, an imprint is usually a "trademark" or a "brand".
In the following image, it seems to be a "trademark" so I would say it's an imprint.
The text "Edison-Bell Records" isn't even printed on the label, so I'd enter an edit to change the release label to "Winner", which would be an imprint-type MB Label.
