Felines yesterday, canines today. Spratt's were a dog food manufacturer that existed until the early 1970's. This sign I think dates from 1950, as MML appears on the bottom. It's on the wall of a local cafe, which previously was a corner shop. I'm surprised that it still survives, as I thought it would either have been removed by now or stolen by a collector or dealer. But it's good to see such things still around.
Are there any old advertising signs still around where you live?
