Of course, you all know of the totally cool case study houses designed as part of a program overseen by the magazine "Arts & Architecture" from the 1940s through the 1960s. They were used as a way to demonstrate new ideas in building and created iconic houses (like these apartments in Phoenix, pictured) which are readily recognized today.
Did you ever stop to think who set up the interiors of those cool houses? Well, it was a Long Beach (CA) furniture company called Frank Bros. You can read more about their contribution to mid-century design here.
