You get the idea there's a restaurant on site, don't you?

There isn't.

It was the delightfully named "Threatt's Restaurant," and some hard, detailed googling - we're talking ten results down - revealed that it was across from the Andrew Jackson Hotel. Maybe. It matters not a whit; no trace seems to have survived. Why was it on this card I don't know; perhaps the owners of the motel and the restaurant decided to go in together to tout the amenities of Southland.

At least we have a small proof of the existence of Mr. and Mrs. Clifford Threatt.
