A smile in his gray mustachio lurks Whenever he thinks of the King of Spain, And the listed tulips look like Turks, And the silent gardener as he works Is changed to the Dean of Jaen.
"The Complete Poetical Works of Henry Wadsworth Longfellow"
Henry Wadsworth Longfellow
The horseman's air was erect and bold; a small but coal-black mustachio heightened the resolute expression of his short, curved lip; and from beneath the large hat which overhung his brow his long locks escaped, and waved darkly in the keen night air.
"Paul Clifford, Volume 3."
Edward Bulwer-Lytton
I should have said a becoming mustachio, such as you may well be proud of.
