Here are two more blotters from the Dale Hastin collection. The first advertises Niagara Falls, reached via New York Central subsidiary Michigan Central. Judging from the locomotive, which appears to be a 4-8-2 (compare with the second photo on this page), the blotter is from the 1920s or even the late 1910s. New York Central bought its first “Mohawk” locomotive in 1916 and, by 1918, owned more than 150 of them.
This war-time blotter encourages civilian passengers to purchase their tickets well in advance of travel, always good advice from the point of view of the carrier. As it indicates that “military demands are growing daily,” it is probably from 1942-1944.
As a bonus, here is a New York Central luggage tag from the lightning stripes era, i.e., about 1948-1960. It is much more conventional than the rather flashy NYC luggage tag previously presented here.
