These are the main publications that resulted from GN’s historical expeditions of 1925 and 1926, including some booklets written by Grace Flandrau (“GF”) that don’t directly relate to those expeditions. One of these, Seven Sunsets, was about the then-new Oriental Limited, while the GN used two others — The Oriental and Captain Palmer and Red River Trails — as Christmas cards in 1924 and 1925. (A different version of Red River Trails was distributed to members of the 1926 expedition.)
