A collection of American sewing machine trade cards, mostly from The American Singer Series, issued by the Singer Manufacturing Co. Each chromolithographed bird card (robin, bobolink, grosbeak, orioles, tanager, thrasher, wren, wood thrush, cardinal and others) has a reverse side with a short natural-history note and a Singer advertisement. The ads cover the Singer 20 child's chain-stitch machine, the Singerlight electric lamp, electric sewing motors, the treadle machines, the needle threader and stocking darner, and a pitch to domestic art teachers. The set also includes cards for the White and Household sewing machines, one of them a puzzle card.
