It's a message that never loses its importance and must have been said in hundreds of different ways over the years, not least in this unusual 1930s Keep Your Teeth Clean print.
The striking design looks quite contemporary but in fact was designed in 1938 in America to promote good oral hygiene. The poster has been selected from the images in the massive archive of the Library of Congress and reproduced by a company called Wallblank. Take a look at their selection of 'vintage' prints for more images in this line, alongside more familiar wartime designs and the See America range of posters.
The print costs between $14 and $24 depending on the size required.
