New Section added: Vacuum tube glow, box scans and artwork

In the spirit of both preservation and exploration, I have added a new section to the the under Photography: Vacuum tube glow, box scans and artwork

Here I will be documenting the artwork used on vacuum tube boxes as well as showing some of the images I have captured of vacuum tubes while they are operating.  I will be adding more images over time as I work through my vacuum tube inventory.
