Maybe try an art school or local art society exhibition?
You could end up making a good investment.
Failing that google image search 'rasterbate' , I did one but had a copy shop print it out on thick red a4 card.

Charley Harper
You can find Charley Harper posters for rather cheap. I have one of birds in my kids bathroom. Do a google search and you will find several places with items for $30 or less.
There are also a number of etsy shops that sell hand made and even limited run pieces that are very attractive.

Even if you don't consider yourself an artist...
...like me, something like this is real easy (just a first try, on my part). I tell people its my "hommage to Jackson Pollock". And he's mid century modern, no?!
Buying art is great, but if you have a piece you did yourself, it can spark people's interest, and you may have a bit more to talk about.

Lustig office, 1945
quote from the website linked below...
Lustig (1915-1955), a modern-design pioneer, particularly inveighed against professional categorizing. "The words 'graphic designer,' 'architect,' or 'industrial designer' stick in my throat giving me a sense of limitation, of specialization within the specialty, or a relationship to society that is unsatisfactory and incomplete," he wrote, about his brief yet variegated career, in the September 1946 Interiors. "This inadequate set of terms to describe an active life reveals only partially the still undefined nature of a designer." He felt that life was too short for such compartmentalization; by age 39 he had gone blind from diabetes, and a year later, he died. Perhaps knowing that his time was limited forced Lustig to excel in many design disciplines and pack a lifetime of experience into half a lifespan.
