Home Ec vacs
That is an amazing AE above!.Not just condition but the rare label.
I was told by an older Elux salesman,now dead,that they would sometimes deliver vacs to home ec depts in the 50s when they were near a particular school.Branches would work about a 50-75 mile area at that time.
I also have some copies of the monthly magazine for home ec teachers from the 50s & 60s.The teachers also had yearly conventions with displays from many vendors with kitchen,cooking/food,laundry & cleaning products.Hoover would donate new vacs every 2 years with much training/teaching material.I was also told by a home ec teacher that they could get a discount on their personal Hoover.Lewyt offered films,poster,etc in the 50s.Elux had more information introducing the power nozzle.Westinghouse(that was already promoting kitchen products)ran ads in the 60s for the ConVertoVac.
