Going through the tons of Electrolux manuals (service manuals, service bulletins, owners manuals, sell sheets, etc.) I ran across this, somewhere I think I also have one for the model G.
I think these continued through the Diamond Jubilee.In addition to the paper fold out that the salesman could carry there were mounted posters for the sales office that could show both the quality features and make it easy to understand when a customer came in years later for service or repair and wanted to know what a bearing or fan or cordwinder spring was.
