This series consists of material collected and received by members of the Hill family, including calling cards, receipts, postcards, programs, certificates, lists, notes, and other items. Blank postcards collected by the Hill family are included here (inscribed postcards are found in the Correspondence series) as well as bound and mounted "art appreciation" photographs and reproductions, including stereoscopic views of various subjects. Of note is Abby Williams Hill’s contract with the Great Northern Railway, ephemera related to the family’s trip to Europe in 1908 and 1909, a list of paintings exhibited for the Great Northern Railway at the St. Louis World’s Fair in 1904, and various notes written by Abby Hill on topics including Native Americans, tuberculosis, and air quality for factory workers. Materials related to Hill’s work with the Congress of Mothers can also be found in this series.

Note that additional ephemera can be found in the series for the Bonnie Smolenski Collection on Abby Williams Hill.
