Tubes (HTT)

Taken at Hamvention, Dayton, Ohio. This is a big amateur radio get-together. They have a "flea" market in the open field near the exhibit halls. This fellow was selling TUBES! Yes, there are still tube radios being maintained and used for amateur radio.

(And they were also selling tube testers, not shown.)

For the Sunday Challenge the issue was context. So, the viewer might ask: where is this? why all these items? these seem for sale, but who buys them?

When I first posted this, I tried to provide some context using words, but we get a little bit of visual context with the grass and vehicle in the background (flea market?). So, where do we go from here?
