Despite the bulky “Emigration” package in “A. Lincoln’s Union Express,” the immigration rate to the United States was actually down during the Civil War. The choice of “Monroe Doctrine” may seem odd in that the Lincoln administration had not fully turned its attention to the advance of the French puppet ruler in Mexico, Maximilian. However, the cartoonist no doubt believed that a Democratic administration would do less. “Pacific Railroad” refers to passage of the Pacific Railroad Act (1862), which led to creation of the transcontinental railroad (completed in 1869). Since Frank Leslie’s was less enthusiastic about black civil rights than Harper’s Weekly, it is not surprising that “Emancipation” is less prominent in the wagon.
