This thesis is interested in the Murine eye drops and Listerine antiseptic advertising campaigns published in Québec magazines between 1925 and 1950, a period that corresponds to the beginning of mass publicity. The advertisements for these body products insist on two selling points: beauty and health. How were these ideas presented by the ad creators motivated by increasing their sales, here is the main question that guides our research. Our analysis is more particularly about the selling strategies concerning the ideas of beauty and health and shows that they are many and varied for each product. Our study also aims at emphasizing the evolution of selling strategies through the context, the norms and the values current between 1925 and 1950. We support the assumption that advertisers could change the image and even the function of these products without modifying their components, by insisting more or less on one particular selling point, adjusting their message to socio-economic and cultural events.
