These characters actually appear in the last panel of FIRST WAVE #1. Alas...in the preview ad, Jenny Cloud is holding a hawk, which seems stereotypical.
The only counter-clue comes when a reporter asks Doc Savage, "Your latest breakthrough--you really believe space flight is doable?" But it's not clear what this refers to. To any manned space flight (which began in 1961 in our reality)? Or to something more ambitious like sustained space flight to Mars and beyond?
To give you an example people are familiar with, look at today's cop shows. Most have a substantial number of minority characters: as law enforcement personnel and as criminals. Why? Because the field of cops and robbers is pretty well integrated these days. If an era of Irish policemen chasing Italian gangsters ever existed, it ended 50 or 75 years ago.
Micah Wright says DC is striving for a "League of Extraordinary Gentlemen" milieu, where the best pulp heroes come together in new/old stories. Problem with that is that it exalts pulp's white-dominated racial politics along with its white-dominated architecture, fashion, and slang. Going back to a pseudo-1939, even if it's really 2010, is like going back to the Jim Crow South. Unless you deconstruct the era's race, gender, and class issues, you're basically touting the white status quo. That wasn't good in 1939 and it isn't any better in 2010.
To be fair, Azzarello is trying to make First Wave more multicultural. But he could've done much more than he did in the first two issues. Having read Chris Claremont's X-MEN and Roy Thomas's ALL-STAR SQUADRON, I'm not particularly impressed with the results.
Sure, the comics that focus on Black Canary, Rima, and the Blackhawks may be better. But it seems the big (white male) three--Batman, Doc Savage, and the Spirit--will predominate. Since the first two issues were mediocre at best, I won't be around to see if the series improves.
