Below is a letter dated 1893 on Harry Rickards' stationery. I'm not sure if it's signed by Rickards or by his brother Jack Leete. The Tivoli circuit was a family affair and Jack managed a lot of the business side.

This is a picture of Harry Rickards from an early 20th Century magazine. It outlines all the theatres he operated in Australia. These included the Tivoli in Sydney, The Opera House in Melbourne, and theatres in Adelaide and Brisbane. As you can see, Rickards had no problem with self promotion.

Frank Van Straten's book on the Tivoli called Tivoli, covers everything you want to know about the history of this legendary theatre chain.
