The model is Janny Goss a Carlton girl, and this
Norma Tullo knit was my favourite jumper in about 1965. Ms Tullo had a boutique on the corner of Toorak Rd and Avoca St South Yarra, and her factory in Richmond had the 'honour' of the council renaming it's street Tullo Place.
My beloved Canary jumper came in a book with another pattern in pale blue mohair of a cardigan with crochet 'buttons' stuffed with cotton wool (I think that model is Georgia Gold),
and that was the more-popular pattern choice of the Melbourne Dollybirds, they were everywhere in it.
