Early Morning on the Avenue in May 1917 by Frederick Childe Hassam is a poignant work from his acclaimed "Flag Series," which depicts the patriotic transformation of New York City during World War I. The painting captures the quiet majesty of Fifth Avenue at dawn, adorned with a myriad of flags representing the Allied nations, symbolizing unity and the collective spirit of the war effort. The avenue itself is almost serene, with only a few indistinct figures and carriages visible, emphasizing the peaceful start to what would become a bustling day. This quietude contrasts with the underlying purpose of the flags, which serve as a call to action and a reminder of the ongoing war effort.
