Lowney's Almond Milk Chocolate Bar Advertisement, 1921

I am intrigued by this 1921 advertisement. The 1920's were a time of rapid change, and schools were becoming larger with some even having school lunch rooms or cafeterias. However, I'm uncertain that it can be considered progress when more and more school lunch rooms were selling Lowney's Almond Milk Chocolate Bars.
