All but one, or possibly two, of these postcards appear to date from the 1910s or 1920s. The first one has an almost completely unrecognizable photograph of San Francisco. While many of the buildings in the picture may still exist, many are gone and the view today is quite different.
Wabash trains from St. Louis connected with Union Pacific trains at Kansas City. This card was posted from St. Louis on May 5, 1915, by someone who says they are “working in the ticket office.” The UP logo on the card dates from 1913 or before.
This card has the “system” logo which dates it to 1914 to 1931. The car in the picture looks to be from the late 1920s.
This card is about the same age as, or perhaps a little older than, the Lake Tahoe card. Unfortunately, the vehicle in the photo is unrecognizable. Tioga Road wasn’t paved until 1937, and for other reasons, including the “system” logo, this card was from before 1931.
This white-border card is a puzzle as it appears to be a lithograph of about the same quality as the Lake Tahoe card, which dates it to before 1930. But the Union Pacific logo on the back dates from 1942.
This is the only one of these cards that is clearly from the post-war era. We’ve seen this photograph on a 1949 menu.
