'T-Bag' ran for several series on Children's ITV from the mid-80s to the early 90s, revolving around witch Tallulah Bag (Elizabeth Estensen) and later her sister Tabatha Bag (Georgina Hale), who both gain their magical powers from a tea brewed for them by their sidekick T-Shirt (John Hasler).

The premise of each series involved various items hidden across time and space, usually hidden in famous historical periods and settings, with T-Bag and the heroine of each of the thirteen series both trying to find them.
