A one-page advertisement for Clark's Mile-End Spool Cotton, described as best six cord thread for hand and machine use. It shows the oval trademark logo and carries a recommendation line naming Bloomingdale Brothers, apparently the retailer. It is of interest for the history of commercial sewing thread and its marketing.

A two-page set of pictures of the Clark Thread Company mill complex in Newark, New Jersey. The first page has two engraved bird's-eye views of the factory buildings, smokestacks and the Passaic River beyond. The second page has two photographs of multi-story brick mill buildings, one in grayscale and one in sepia. The only text is the company name.

A scanned collection of 36 pages of chromolithographed Victorian trade cards advertising Clark's Mile-End and O.N.T. spool cotton, made by the Clark Thread Company (John Clark Jr. & Co.). The cards show children, animals, verses, landscapes, famous people, the Jumbo the elephant series, and Columbian Exposition 1893 views. Some carry the stamps of local dry goods merchants. The pages are image-only and have no weaving content.
