Some additional thoughts:
In reality, today's conventions are much, much larger. I estimate the San Diego Comic-Con is literally (not figuratively) 1,000 to 10,000 times larger than this convention was.
And a couple of corrections:
All in all, it was a typical episode of The War at Home. It was fun seeing the posters on-screen, but I doubt they'll register with anyone who didn't know about them already. Oh, well...every little bit of publicity helps.
