This is 469 West Sullivan Street.  In 1959, this was Porterfield City Feed Company, next to City Poultry and Egg Company.  CP&ECo was on the corner of Sullivan and what was then Island Street (It’s now Mission Street).  The buildings are currently derelict.

When I was a kid, I had a paper route in downtown Kingsport.  One year, the Kingsport Times-News, then located on Market Street, held some sort of contest and I ended up winning a certificate for a turkey from CP&Eco, just in time for Thanksgiving.  It was, as I recall, a mingy turkey, but it was quite welcome, since my stepdad wasn’t having a particularly good year.  My stepdad never had a particularly good year.
