Old Oregon Trail, Irvin "Shorty" Shope, 1948
Done by the western cartoonist Irvin Shope, this map is visually interesting but also a great reference. While it focuses on the Oregon Trail on its centennial, it touches on all the West and shows twelve other key trails and routes, from the Spanish trail, to Lewis & Clark and Butterfields Denver Stage line.
Condition is good with some repairs to marginal tears . Image size is 17.5 x 24.5 (inches).
