Hi David, Red seal Victrola labels were the more expensive records at the time. They were one sided until 1923 when a second side was added. Some have blank sides, some have ornate designs on the blank side, it was Victors way of getting more money and maintaining the prestige of this series. The Caruso records are good, my favorite is Dreams of Long Ago which was sung in English. Many record companies had foreign series.Corrections are welcome. Steve >> A few have red Victor labels.
