I've always been an ATSF fan so the "DF" and "Shock Control" stencilling were two separate items.
When I was in HO, and in high school, one of my modeling railroad friends was modeling a rundown Pennsylvania shortline struggling to get by. I stole a broken outside-braced wood-sided 40' boxcar out of his junk drawer and gave it back to him on his birthday relettered for his railroad and emblazoned "Future Shock Control - by Toffler' on the sides (in ATSF lettering style)....because his broken-down line couldn't afford it yet. What can I say, we were in the same english lit class!
So if you're trying to save money....just a thought.....
But yeah, they were two separate features. I don't know of anybody else that printed them any bigger than Santa Fe though.
