Newspaper question

I have a puzzler.

All of the small buildings here (fuel house, chicken house, carriage house, etc) have a layer of metal under the siding. The metal is thin and shiny. Think furnace trunk line material. All of these sheets are newspaper sized and printed with newsprint. The printing is on the metal with ink, not raised. I originally thought it was the printing blanks off of the drum, but it is not reversed and done with ink. What are these?

The neighbors shed is done with the same thing. Someone must have had a friend at the newspaper. She doesn't recall how that got there and it is a century farm so it must have been discards they got free or something. I have read the obituaries when I cut a window opening but I can't recall the date on it. I want to say 40's. Anyone seen this before on old buildings?

Oh, and I would be using my TRACTORS right now but it is raining and too wet for field work. :+)
 
They are "offset printing plates" the (positive) plates are inked, the ink is then transferred to a rubber-covered drum (negative) and the which then transfers the ink to the paper, creating once again a "positive" image.

^ this. My dad was a printer in the days of cast lead type on flat-bed presses and linotype typesetting machines. He never made the jump to offset. Wish I had pictures of the old print shop.
 
The printers couldn't use the plates for another print job. No recycling back then, so they used to give them to whover wanted some aluminum plates.
 
I did both in my first job after I left the Marine Corps. Started out in letter press and then resurrected a 1250 Multilith and went on to run a variety of offset presses.
