While this typewriter looks like it is an ordinary Brother compact portable, it is a model that is rare to find in Seattle--a Kmart portable. (Strangely, they are easier to find in Australia). I had spent four years looking for one of these at Goodwill, but never did. (But then again, there were only two Kmart stores in Seattle...and we had Sears and Penney's stores throughout the city)
(Yes, this is definitely a 1970s ad, based on the plaid bell-bottoms. Also, notice that BELLEVUE is misspelled as "Belleview" [sic]. I have always wondered what Bellevue was thinking when they chose their name--see http://en.wikipedia.org/wiki/Bellevue_Hospital_Center -- America's oldest hospital, founded in 1736--what a strange name for a city, yet there are 53 cities and communities named "Bellevue" in the world. Although I do find it funny that Bellevue, WA is called Bellevue, there are many worse names--for instance, Issaquah was originally named "Squak")
