Teenage Mailbag was an Australian television series which aired in 1957 to 1958 on Melbourne station HSV-7. Information on this series is scarce. According to a 2008 article in The Age, the format consisted of Ernie Sigley, Gaynor Bunning and Heather Horwood singing requested songs in a 15-minute slot, and later expanded to an hour. The one-hour version became the series The Teenage Show (1958-1960?). At one point, the series aired at 7:15PM, preceded by another 15-minute series titled Take That and followed by an American program (The Adventures of Rin Tin Tin).
It should not be confused with an unrelated 1960s series by the same name which aired on TCN-9 in Sydney (see Teenage Mailbag).
