The corresponding article described it as a "former A&P and Fas-Chek" (the latter being a local chain), which certainly makes sense. I'm guessing that it was a late '50s-era store that was given a cursory makeover into the Centennial style after the fact.
The side of the building has vertical ridges (somewhat similar to this), although what it looked like when it first opened is anyone's guess. Is there anything else interesting that might be said about this particular store?
