The 2nd label variant is by far the most common, indicating the popularity after the repressing of the record. The 1st edition has the comma after Corporation, and the last edition has the patent legend below the logo.
Although this record came from a colored band, it must have been a big seller among the white people in 1921, see uploaded full-page OKeh ad in Talking Machine World, July 15, 1921:
THE NORFOLK JAZZ QUARTETTE is another lucky number for OKeh Dealers.
Their music is best described as improvisations that are unlike any other. It reflects the
original negro folk songs, but to the monotonous chanting is added more harmony and
weird jazzed chants.
The initial release of "JELLY ROLL BLUES" totalled a sales four times greater than
any popular hit in that bulletin. These figures forecast the great possibilities in profits
for the trade.
You may be interested to know that it isn't the colored race which is responsible for this
jump in record sales. The big demand comes from the white people.
We see in this group a means to boost sales, and because this is so evident we are getting
ready to forcefully push their records. There will be a generous distribution of literature
and advertising. Everything will be done to help make their records popular.
