This item is a fully hand-knitted Cowichan sweater believed to have been made in the early 1950s. It is a practical item intended primarily for everyday use, such as warmth and work, made before the full-scale mass production and commercialization for tourism. The dolphin motif is a design seen only during the transitional period when interest in the post-war West Coast culture and view of nature began to expand from the traditional designs centered on land animals such as deer and eagles. It is thought to reflect the living environment and values of the time. This item is not merely a patterned garment, but a piece that should be regarded as a hand-knitted product that integrates craftsmanship, daily life, and warmth. 【Production Background and Value】 Cowichan sweaters from the early 1950s were mainly fully hand-knitted by individuals or small communities, and were products of an era where the maker's discretion was largely retained in design, knitting, and finishing. This item has features such as: ・Unevenness of the knit ・Fluctuations in color changes ・Extremely dense weight These characteristics clearly indicate the nature of North American knitwear before industrialization. Individuals with these conditions are few in number. 【Differences from Cowichan Sweaters from the 1970s and Later】 Many Cowichan sweaters that have been distributed since the 1970s have undergone division of labor and semi-industrialization, and are fundamentally different from this item in the following respects: ・Standardization of knit, size, and design ・Use of fully degreased and lightweight yarn ・Design that emphasizes decoration, assuming tourism and fashion purposes On the other hand, this item retains the fully hand-knitted nature before mass production, the weight of a practical item, and a short length design. Even though it is called a "Cowichan sweater," the production philosophy, purpose, and cultural positioning are different. 【Details】 ・Dolphin (marine) motif ・Shawl collar ・Short length (intended for work and warmth) ・Brass zip used in Talon's 50s 【Actual Size (flat measurement, approx.)】 ・Shoulder width: 45cm ・Body width: 53cm ・Sleeve length: 63cm ・Length: 60cm 【Condition】 ・Good condition for a hand-knitted vintage item ・Almost no signs of use.
