1964 Article. 'ONE first-class little company whose name few people know is Cowan de Groot, among the fastest growing firms in the toy trade. They import toys from Hong Kong and all over the world and sell through Woolworths, other chain stores, and mail order firms. Mr. Sam Cowan, who started with his partner, Mr. Albert de Groot in one room in London's City-road just after World War I, told me: "We specialise in low and medium-priced toys." That means they capture the all-the-year round trade from mothers and fathers who spend a few shillings every Saturday to keep the children quiet. Their profits have doubled since 1960.
