I came across this information in the Spring 2019 edition of the Lincoln Forum Bulletin:
"A 30-inch high, original bronze bust of Lincoln - the work of New York sculptor Frank R. Porcu - has been gifted by the Forum to the South American township of Lincoln, Argentina.
The town - some four hours northwest of Buenos Aires - is believed to be the first municipality outside the United States named for Abraham Lincoln. The designation was ordered by Argentinian president Domingo Faustino Sarmiento (1811-1888), a passionate admirer of the American president. Sarmiento went on to write and publish a Spanish language Lincoln biography."
