Ohya (ohio)
is where Hoovers were made.
Remember the door to door vacuum cleaner salesman, like when Moms mostly stayed home?
Whenever a new housing plan went in, they were in there along with the milk man, Fuller brush, Kirby, Rexair (Rainbow), Filter Queen, etc.
California was really on the baby boom grow.
Compacts and Revelations made in El Segundo also may have been sold door to door.
Then, from the 80's, Electrolux USA relocated from Old Grennwich Connecticut to Dallas Texas.
Of course, if Mom ventured into a "Good Housekeeping" shop, major appliance store, or other vac. shop, there were Hoovers, Air Way's from Toledo, along with their second brand similar in shape to a Filter Queen, Royals, and Eureka's from Illinois of course. Sears was also becoming the largest retailer.
