A single-page stock certificate issued by The American Thread Company certifying that Gilbert J. Goulett owns shares of its common stock. The certificate has an ornate decorative border, '100' medallions in the corners, a thread spool vignette at the top, a circular seal and handwritten signatures. It is business ephemera relating to a thread manufacturer, with no weaving content.

A hand-colored picture postcard showing the Old Mill and canal of the American Thread Company in Willimantic, Connecticut. It shows a white multi-story mill building beside a stone-edged canal, with grassy banks and trees in autumn and green foliage. The only printed text is a caption naming the company and location.
