the poster that this incredible illustration is based on is extremely striking. but while searching for it, I also found earlier posters for conveying this message along with a corresponding one for summer, and I fucking love them. absolutely lovely graphic design work. (both are from 1924, artist is Austin Cooper)
the one I was looking for originally also has a summer variant. (artist is Frederick Charles Herrick: 'it is warmer below' is from 1927, 'it is cooler below' is 1926)
