Like the kind of stuff you'd see at the turn of the century (how people though things would be) with people in personalized jet packs and all the buildings with glass and domes. I found some of Windsor McCay's work kinda like what I'm looking for:

Haha, silly past people, thinking we'd let women read or get an education!
Before Cat kills me, j/k. This stuff is pretty fascinating, particularly the robotics and in-home predictions. Like how the original Star Trek was behind the times on some things (data storage, communications) and so off on others (warp, spaceships).
I googled the retro-futurism and found a ton of results, thanks. But still no posters. I could just take some of the pics to Kinkos and have them blown up though.
And that website paleofuture was hilarious. That's pretty much spot on as far as what I am looking for. I just wish they were a bit higher quality.
