Poster from the first Humanist Community Darwin Day, in 1995:
As described at the Humanist Community Website:
Darwin and Human Origins
Donald Johanson, prime researcher in anthropology, discoverer of "Lucy", presents an exciting tale of his adventures finding "Lucy", and related matters including the importance of Darwin in his own life.This was the Humanist Community’s first Darwin Day celebration. It developed out of a 1994 brainstorming session when Bob Stephens suggested the idea of celebrating Darwin Day as a way to acknowledge the importance of science in the modern world. Sandy Gardner chaired the first Darwin Day planning committee. The program was adopted by the Board early in 1994. This Darwin Day event was aided by funds from a James Hervey Johnson Charitable Educational Trust grant.
