These images come from Number 3 and was printed in 1946 as Miss Australia as a model and mentions her recent trip to Britain. She was in the UK in August 1946 so I think Number 3 dates from September/October 1946.
The books were meant to be the best in beautiful knitwear designs but they also tried hard with the book itself. The paper is not the usual flimsy post-war type but is smooth and very cleanly printed. There were never fewer than 44 pages to them and featured a range of garments, all specially designed for Dorette.
Update: A lovely Raveler has one numbered 27 so these lovely booklets went on until at least May 1950
