That set works pretty good... even without the power cord!
I like the way the artist included the lit heaters on the 5U4's... very good detail! Who's the artist anyway? He should do some more! Was this something from many years ago in a book or magazine, or was this recently created?
I've seen this photo somewhere else, but slightly different. On this photo, there is a CBS tag hanging from the back of the set. The other I've seen does not have the tag.
