One set of men's Jaeger beige cashmere and wool underwear, size 42, belonging to William Lyon Mackenzie King, consisting of of a jersey-knit shirt and a pair of bottoms. The shirt has three buttons with button placket reinforced with woven material. Mackenzie King's Initials “W.L.M.K.” are embroidered in red on the front right bottom above the ribbing. The shirt has a white woven label with red letters at centre inside back neck: “Jaeger, Pure Cashmere & Wool, Made in Gt. Britain.” The bottoms close with a three-button fly and have a lace-up gusset at centre back. The waistband and fly are reinforced inside with woven material; the gusset has two sets of embroidered eyelets laced with a white ribbon. Two sets of horizontal double loops made of woven fabric are sewn down outside at the waist on either side of the fly, possibly for attaching to the shirt. The T. Eaton Co. catalogue of 1920-1921 describes these as “brace loops.”[1] There is evidence of something having been sewn above the shirt ribbing, front left side, as thread knots remain. The bottoms have a white woven label, inside centre back, with red letters. The word “Jaeger” is at the centre of a diamond shape bearing text on all four sides: “Health & Comfort, Warrented Pure Wool.” Below the diamond is a ribbon shape bearing text: “Patent Unshrinkable Process,” and below this on the bottom edges is: “Made in Gt. Britain.”
