Many years ago tongue (but not from a can) was a normal lunch meat in our house along with sour onions right out of the barrel from the deli on Belair road.

I loved taking my time eating the onion by peeling off portions of a layer at a time and enjoying the eye squinting caused by the sour brine while by sister would attack it like a McIntosh apple.

Found this article about the store:

Located at the foot of Washington Street across from the levee, the Joe Gow Nue store was one of the first and largest Chinese grocery stores in the Delta around the 1920s, serving also as an informal gathering place for the Greenville customers. It sold local as well as imported foods, and other general store items.

Thanks to JidThorax for finding the newspaper ad! When was it published? Could Joe have had a third location at some point? The addresses on the ad don't look at all like the photo location, which appears to be by the river: the barren hillside on the left of the photo is almost certainly the Mississippi levee, many blocks from Broadway or Washington Streets.

Both of Joe's stores are gone now, but he seemed fairly successful.
