These blotters from the Dale Hastin collection all advertise C&NW trains that reach California via the Union Pacific from Omaha. PDFs of the blotters are about 400 to 600 KB in size.
The tiny numbers in the lower left corner of this blotter suggest that it was published in 1910 and that 15,000 copies were made. The date is plausible as the Overland Limited began operation in the late 1890s and the Los Angeles Limited in 1905.
Ten thousand copies of this blotter aimed at San Francisco travelers were apparently printed in 1930.
Similarly, the code in the lower left corner of this blotter suggests 25,000 copies were printed in 1932. Again, the date makes sense as all the trains listed were operating in that year.
This 1936 blotter, of which 100,000 were apparently printed, advertises free drinking cups for coach passengers on the Challenger. That train was inaugurated as a low-cost alternative all-Pullman trains such as the Los Angeles Limited in 1935.
Another 50,000 copies of a nearly identical blotter were printed in 1937.
The UP/C&NW City streamliners went daily in the late 1940s, so this undated blotter dates from then or a little later.
