Here's another one for Silver Spring, Singular's Googie file: Marvel Cleaners, located in this 1960's-era Mid-Century Modern building at New Hampshire and Randolph in Colesville. (Why is it that dry cleaners are always the most architecturally adventurous?) My family's been going here since we originally moved Up The Pike in 1998, and even then I was always puzzled by this strange building.
There are a lot of things I love about it today: the giant neon letters running across the front (which are still lit at night) and the three hexagonal signs below. The floor-to-ceiling windows (though look closely at the bottom and you'll see most of the louvers have either fallen out or gotten stuck) and the four lamps on the left side that draw the eye to an otherwise blank wall. The asymmetrical composition of the entire building, which directs customers to the door without having to put it on the front.
This place has definitely seen better days, though if Marvel were ever to leave it, I'd hope to see it fixed up. The suburban roadside buildings we put up fifty years ago are no less cheaper than the ones we build today, but when done right they look so much classier than the crap that followed.
