i would not consider anything mid-20th century to be "modern". i tend to refer to the 20th century using terms like "the previous century", with the context that the previous century existed before the modern time period. we can start in the 1990s, i guess. but, certainly, the middle of the twentieth century, which was 1925-1975, would be considered the distant past and not remotely modern by any discernible standards.
further, this is a time period where the culture was utterly shit. it was a low point in science, a low point in politics and a low point in art, coming out of the high point of the progressive era and entering into the high point of the 70s-90s. i certainly don't want to buy a 1960s fashioned sofa. yuck. who would?
so, i don't get this. i don't see modern anything. i see something badly dated.
