I tried to identify the creator of the incredible molded acrylic-walled structure in this photo before the wife and I headed out of town for a kid-free, backcountry, weekend, but no luck.
It's on the wall at MoMA in New York, second floor, between the cafe and the Cullman Education building [which, more later]. The only caption is, "Sculpture Garden, c. 1970."
Judging from that big elemental abstract sculpture in the background, I'd guess this was a temporary sculpture exhibit, not an architecture & design show. If anyone has any vestigial memories of visiting this as a child, or any other leads, definitely let me know.
