Zwirner's husband-and-wife show of the Swedish artists Mamma Andersson and Jockum Nordstrom works, as many marriages do, because each person has plenty of space. The exhibition takes the form of his-and-hers solos, joined by a hallway of collaborative works on paper. It also helps that the artists share some things -- a folksy, intuitive style and a rustic, earth-toned palette -- without sharing everything. Mr. Nordstrom cherry-picks figures and settings from Cranach, Ensor and obscure Scandinavian artists, while Ms. Andersson cultivates the decorous domesticity of Vuillard and the Nabis.
