HIGH GRADE
RED SEAL GENNETT LINE
Starr Piano Company, Richmond, Ind., An-
nounces Release of Red Seal Gennetts
Popularly Priced at Fifty Cents.
A new addition to the Gennett record line was an-
nounced by the Starr Piano Co., Richmond, Ind.,
through its Chicago branch at 234 S. Wabash avenue
early this week. Heretofore the Gennett line com-
prised only the green and blue seal, and priced from
seventy-five cents to a dollar, but the Richmond linn,
in complying with the demand for a quality record
at a reduced price, has added a new number which
will be known as the Red Seal Gennett. The price
of the Red Seal records has been set at fifty cents.
Manager Hunt, of the Chicago office of the Starr
Piano Company, in explaining the object of the new
records to a Presto reporter, said: "In order to meet
the present-day demands of the public for a quality
product at a lower price, we have produced an ideal
record which will be known as the Red Seal Gennett
and will sell at fifty cents.
"The latest hits last only for a period of two or
three weeks and then the record is laid aside and an-
other hit purchased. As a result the trend of record-
buying leans towards the lower-priced record, espe-
cially so with the song hits. To meet this condition
is the part of the Red Seal Gennetts which will be of
the same fine material that characterizes our blue and
green seal records. Dealers and the public have taken
to our Red Seal records in a most convincing fashion,
and it is evident that our sales will receive a great
boost."
