They look like openings for neon tubing to me.

I initially found this sole photo of the old Wyatt's Typewriter shop.  (Note the "salesman wanted" sign at the lower,right corner of the front window.  No info./caption with this photo.  What ever street is was located, the shop had a street address number of "541".
.


After some searching, I found some other photos of the same store with info. that it was located (and not just nearby) the Copley Square area of Boston, MA.  Larger photo shows more of the building.  With the car in the forefront, looks like the photo was from the 1950's or so.  Note the Lewandos Cleaners to the left of the typewriter store has a street address of "543".
.


Continued searching found more photos taken along that street along one of the edges of the Copley Square.  I pasted these two photos together.  Note the Volvo P544 also curbside.  This Volvo model had a production run from 1947 to 1965.  Futher diging into old news files indicates much of the housings/buildings along the perimeter of Copley Square met the wrecking-ball in the 1965 time-frame.

I did a Google street-view tour all around the perimeter of modern-day Copley Square and could not find such a row of these old buildings that survived.  Most are now concrete monoliths from the early late 1960's and the early 1970's and even more recent.

The Boston Cash Register Exchange was located at 1288 Washington Street, Boston MA since 1932.

Photos 1 and 2 show the old shop location awaiting the wrecking ball in 1964-1965 :

A current view of the old 1288 Washington Street location shows the new building.  It would be the 2nd. or 3rd. doorway from the left corner :

But it is not all sadness with the wrecking ball coming and going.  The Boston Cash Register Exchange found a new home at 264 W/ Broadway, Boston, MA.  They are the store front partially hidden by the tree along the street curb.  So it is still in business...since 1932.  It does not look like typewriters are part of their product offerings, anymore.

In the past year or so, the shop was acquired by the East Commerce Solutions business group...but name of the shop remains as back in 1932.  Here is the new Company's web site.  In the "About Us" section, the acquisition is announced.

In Post # 9, I was hoping to bring one or both of the locations for the Continental Typewriter Co. to life with some period-photos. 

Failing that, I found these old letters dated January 1929 between the 847 Broad Street store location in Newark NJ and a rental-machine customer.

Voices from ghosts of an old typewriter store...

Ed Smith (known as Smitty) started in typewriter repairs in 1967.

By the time computers hit big, Smitty had a total of 3 locations around Houston, TX.  But in the 1980's he was forced to shrink back to his one, original location.

In 2012, Smitty was featured in the Houston Chronicle article when he was 75 years old, then and still working after 3 previous heart attacks.

Unfortunately, I think Smitty passed away in August 2021, at the age of 84 years old.

Here is a current view of the old typewriter shop location.  The main house looks boarded up and being gutted.  The typewriter shop (what may have been a garden shed in its previous life) is still there but with bars on windows and the door.
