Company Names, addresses, dates:
  Thompson Brothers Dairy, Vienna, VA

Notes:
The Thompson Brothers dairy had advertisements in Fairfax high school yearbooks between 1938-1945.
I'm not sure who the Thompson brothers were, but the 1940 US Census lists Joel F. Thompson and Stanley E. Thompson as 2 brothers living in Providence Fairfax, with their occupations as Dairy partners.
Effective Jan 1st, 1936, the Thompson Farms Dairy took over the Ankerdale Farms Dairy (both dairies were in Vienna VA)¹.
There was also a Thompsons dairy in Washington DC, which may or may not have been affiliated with the dairy in Vienna. It's hard to sort out the difference between the DC Thompson dairies and the Vienna Thompson Brothers dairy when researching.
