'Yes, No, Maybe': National Gallery exhibit shows printmakers' decisions along the way

"Yes, No, Maybe" sounds like an exhibition devoted to something about binary code, to computer languages or the "if, then and therefore" of logical analysis. But it is a show highlighting the work done at Crown Point Press, which for a half-century has functioned like a think tank, artistic incubator and invitation-only haven for artists who want to experiment with the rich complexities of print making.
