This image shows the famous cherry trees in bloom as they frame the Washington Monument across the Tidal Basin in Washington, D. C.

The description states:
The Washington Monument. The white marble shaft rises 555 feet and may be reached by elevator in 70 seconds. The cherry trees ordinarily bloom early in April.
–For a number of reasons, the monument, started in 1848 was not completed for forty years. The original design had a colonnade and a flat top, but the colonnade was abandoned and a pyramidion was added to the top.
This card was used and is dated 16 July 1966.
