Here's some things to try, especially if you're internet shopping:
run your google as -- mid century modern -- lots of hits, and for browsing, or to contact a dealer, here's one:
www.tri-stateantiques.com also run googles or auction site searches as -- eames era furniture --
That will get you into the 40's, 50's.
And try words such as: "vintage", or, "moderne" furniture. Best wishes, KB :unsure:
