Most postcards are as realistic as can be.
This one must have been done by a true artist who used artist's license to create this junction in his own way.
Having been trained as an artist and teaching art for many years, I find this one interesting. It's almost like folk art.
The subject? It is the Junction of U.S. Highway 64-67 Beebe Arkansas probably 40 or 50 years ago. Anderson's Grill was a great place to eat. Folks from all over congregated there for excellent steaks and salads. I remember the salad dressing was REAL Roquefort dressing, not blue cheese.
I think the Grill finally burned but we'll have to ask the experts whether that is right. Everyone who liked fine food mourned when it ceased to serve.
