Shelley in an ad for Columbia Minerva, 1967
Shelley appeared in an ad for Columbia Minerva in 1967 called The Rambling Rose. It featured "lovely embroidered sweaters" that had a rose design on the sleeves. They were perfect for cool spring nights and could be made by anyone, because it was available in a knit kit (no. 4112) sold by, who else, Columbia Minerva. Nothing was "nicer for spring"; and Shelley sure looked nice in that sweater.
