Cattle grazing (or at least standing around) in Lebec, 1917-1919. Real photo postcard.
The cancellation date (at Lebec) is illegible, but there are a couple of clues as to when this postcard was mailed:
(1) During U.S. involvment in World War I, specifically on November 2, 1917, the 1 cent postcard rate was raised to 2 cents.
After the war ended, on July 1, 1919, it went back down to 1 cent.
The rate was raised again temporarily to 2 cents from April 15, 1925, to July 1, 1928, but this postcard is more likely to have been mailed between 1917 and 1919 because...
(2) The carmine-colored Washington 2 CENTS 2 stamp was issued no earlier than 1908 and no later than 1922. (A philatelist could probably pinpoint it even more closely.)
The stamp box could also provide a date clue, but we can't see it without removing the postage stamp. The paper manufacturer, Kruxo, was active from 1907 to the 1920s.
The postcard was sent from "Doc" to "my pals in the postoffice, Oilfields, Fresno Co., Calif.," with the message:
Dear Margaret & Bill —
Still going up and all is well. We've just had a talk with our "friends" under the trees.
Presumably the "friends" are the cattle.
