Stroll down Jackson Blvd. in the Chicago Loop and you’ll come across that deco masterpiece, the Chicago Board of Trade Building, 141 W. Jackson. With Ceres atop, put there by designers who knew their ancient lore. Wish it was easier to get a close look at her.

As mentioned, the place was crowded with Open House Chicago attendees, as seen in the magnificent lobby.

In one way, that was good. There was more time to eye the details. In this building, the deco is in the details.

No mail passes through these boxes any more, which is too bad. Back when I had an office in 35 E. Wacker, one of the pleasures of being in the building was passing through the lobby when I had something to mail, and slipping it into the imposing, ornate box, whose very presence announced: This Is The U.S. Mail. By the ’90s, a thing diminished, but not yet relegated to a has-been.

In the basement is the building vault, formerly used to store valuable commodities. The vault door is impressively massive.

Inside, an array of smaller boxes. Empty now.

Room enough for an upscale bar, I think.

The trading floor. Not busy on a Saturday.

Hardly looking the way Stanley Kubrick saw it in 1949, when he took this picture for Look magazine (reportedly in the public domain these days).

Those guys look like they might have traded a few pork belly futures in their time.
