B. B. Hume's Automobile Garage, at 330 Scott. That's a Hupmobile (Wikipedia), on the 1916 Hupmobile United America Tour.

 

You're looking down Pike, from Madison toward Scott. That's M. L. Swetman and Sons on the left, selling Nashes. John Hanauer is selling Ford's on the right, and Covington Buick is in business straight ahead at 620 Scott. In the 1937 flood.

 

The 1945 Covington City Directory lists a Louis Meyer Motor Company, a Packard dealer, at 114 E. 7th. There's no Covington Motor Company listed. Same place? Don't know. Also, there's more than one town named Covington, so this one's iffy.

 

This one's not iffy. That's the Packard dealer, Louis Meyer Motors, on the left, at 114 E. 7th. c. 1930's
