I have a "Special" red-label 78 record that has, "Rodeheaver Labortories, Chicago, IL" listed at the bottom of the label. The artist is Ozerie Hall, and he whistles two songs. The main address is a local one, which is listed right under the title. There is a number lightly "scratched" in the label- 7041. Could someone please tell me around when the record was produced and whether or not it was recorded in Chicago, or locally? I appreciate any help because I have been working on an article around this record for a month now.
