A few years ago, I bought a piece of literature which I had never seen before and will probably never see again. being not a collector of paper myself I scanned it in so I would have the information it contained, and then sold it to another collector. with his permission I have been authorized to share a bit of it with you.
Thank you Scott McC.
in this rare piece you can clearly see that somewhere along the way, what we refer to as a Safety Streamline is clearly considered by Huffman as a Super Streamline.
I'm still looking for information as to just what if anything this means.
