year. A Canadian reviewer considered it outstanding, and US reviewers thought Ambrose was "delightfully droll", "just as amusing as Ferdinand the Bull". One US reviewer wrote, "Never did kangaroos look like [this]. But we would not have it otherwise for Ambrose in his blue trousers and wearing a suggestion of a yellow hat between his enormous ears bids fair to captivate a very young audience." Australian reviewers also liked Ambrose Kangaroo, finding it an "irresistible story", which "will entrance the small fry". Ambrose went into several Australian editions, and returned in further books in Ambrose kangaroo has a busy day (1944), Ambrose Kangaroo goes to town (1964), and Ambrose kangaroo delivers the goods (1978). From 1945, MacIntyre also drew an Ambrose Kangaroo comic strip for The Sunday Telegraph, Sydney, for about seven years, and created an Ambrose Kangaroo TV cartoon, which screened on ABC TV from 1958. Cartoon strips MacIntyre also created several other comic strips during the 1950s. One featured George, "a studious little boy who wanted to learn all about Australia", published in Melbourne; Annabelle, published in the Australian Women's Weekly, a "gay, irresponsible, exasperating, far-from-perfect secretary ... [who] you can't help liking"; and Mother, a weekly cartoon in another women's magazine, whose "hardships and experiences are mainly autobiographical", according to MacIntyre. Informational picture books Following the US publication of Ambrose in 1942, MacIntyre was asked by Scribners to write about Australia for an American audience, as many American servicemen were based in Australia, and their families wanted to learn about the country. Susan, Who Lives in Australia was published in the US in 1944, and subsequently published in Australia in 1946 under the title Katherine. The main character was a small girl who lived on a sheep station and had a holiday in Sydney. MacIntyre travelled to America in the early 1950s to meet with her publishers there, and to learn about the reading tastes of American children. Her success in the American market boosted her status in Australia. Two later revised editions of Katherine were published in Australia in 1958 and 1963, and all were warmly received, with reviewers in 1946 describing it as charming, while a 1958 reviewer called it "one of the most delightful Australian books issued for a long time. Lively, sunny drawings of pets, people and recognisable places and an agreeable rhyming text will make it a favourite". Muir's A history of
