Motor is an American motorists magazine. It was founded in 1903 by
William Randolph Hearst, and published by Hearst Corp. It is still in
existence, but went for digital only in 2021 (information from
Wikipedia). This is one of a series of 1921/1923 covers by Howard
Chandler Christy. Everything works here: the girl's face, the setting,
and the contrast between the red and the bluish pastel colours.
