This was a bit strange for many visitors to the Chicago show.

The first booth along the right wall invited attendees to buy Marvel stamps at that booth. But after the Friday morning event (unveiling stamps that had already been unveiled a couple weeks earlier in San Diego) and its follow-up at that booth, it was an empty site by the time I got there. Except for the sign and a few blow-up images of stamps. Postal Service, we love you -- but you could have sold a bunch more stuff, if you'd done more.
