The Banner of Light was an American spiritualist journal published weekly in newspaper format between 1857 and 1907, the longest lasting and most influential of such journals. It was based in Boston, but covered the movement across the US. The paper included a page that gave messages received by its resident medium, and letters from relatives confirming the authenticity of the messages. It also included articles on spiritualism, book reviews, transcripts of lectures delivered by prominent spiritualists, notices of meetings and letters from readers. https://en.wikipedia.org/wiki/Banner_of_Light
