[ Lewis / Main Street ]
Sinclair Lewis (1885 - 1951) was the first American writer to win the Nobel Prize; this, a largely satiric look at small-town life, is his best-known novel.
Chapter 15, section 7 has the novel's only reference to Newfoundlands:
The parlor was distinguished by an expanse of rag carpet from which, as they entered, Mrs. Bogart hastily picked one sad dead fly. In the center of the carpet was a rug depicting a red Newfoundland dog, reclining in a green and yellow daisy field and labeled "Our Friend."
You read that right: a RED Newfoundland... :)
