As part of the series of Political Handbills, Ephemera, and Election Materials, Organizational Materials is perhaps the most general subseries. It includes print ephemera from a number of different groups that, while perhaps subscribing to political affiliations, were not official political parties; this might include groups that collected donations for different causes. The groups in this subseries could also be entirely unaffiliated, as with a painting school. Overall, included materials range from donation envelopes and letters to advertisements, as well as other forms of print ephemera.
