DOLES </div> <div class="node-body article-body">Still in a state of depression, the United States saw its unemployment remain high throughout 1935. With tightened budgets, American advertising shifted its look, focusing more on the consumer than the product, reflecting aspirations of the time, but not directly mentioning the economic struggles. Depression-era audiences desired clear and simple advertising, and print ads morphed from long testimonials to short and straightforward headlines with bold imagery. Take a look at a few of the many advertisements that graced the pages of HPAC Engineering. </div> <div class="field-content-focus"> <span>Content Classification:&nbsp;</span> Curated </div> <div class="og_rss_groups"></div><p><a href="http://hpac.com/galleries/gallery-vintage-hvac-advertisements-1935" target="_blank">read more</a></p> http://hpac.com/galleries/gallery-vintage-hvac-advertisements-1935#comments Galleries Building Controls Heating Humidity Control IAQ & Ventilation Motors / Drives Piping / Pumping Wed, 29 Apr 2015 16:52:00 +0000 16341 at http://hpac.com GALLERY: Vintage HVAC Advertisements, 1933 http://hpac.com/galleries/gallery-vintage-hvac-advertisements-1933 <div class="field-byline"> By ASHLEY M. DOLES </div> <div class="node-body article-body">With America’s economic depression at its worst, unemployment skyrocketed in 1933, leaving one in four U.S. workers without a job and creating great unrest within the nation. American advertising was devastated financially during this depression and shifted from a self-indulgent, beautiful style to heroic imagery of working-class salesmen.
