On 21 May 1940, Annie S. D. Maunder mailed the original drawing of the celebrated ``Maunder Butterfly Diagram" to Stephen A., and his daughter Margaret L., Ionides. Later that same year Stephen and Margaret gave the diagram ``on indefinite loan" to Walter Orr Roberts, then the Superintendent of Fremont Pass Station of the Harvard College Observatory. The framed diagram remains on display today at the scion of that organization, the High Altitude Observatory of the National Center for Atmospheric Research, in Boulder Colorado.
Drawing upon the original correspondences, this contribution recounts the story behind the travels of the ``Maunder Butterfly" during the second World War.
