It turned out that there was some identification on the reverse, none the less, but it is not enough that I have been able to locate the person in online databases.
In the corner is what may be a date, but the writing is so squiggly I can't quite decide what it says. Also the initials POV are shown, which I think may stand for "Point of View", which I've seen before on this style of community snapshot.
On the back, written in block letters is "At El Campo Tex, V A Foster and Pet Pig".
Every time I look at this photo, I think Mr. Foster is saying "Nothing strange about this….I'm walking muh pig!".
