Boston Printmakers, Cyclorama Building, Boston Center for the Arts.

Prints are unappreciated creations. But this vast and varied collection, the Print-makers' annual effort at reaching the public, is a winner. The exhibit is an eye-opener; the unrealized possibilities of the graphic medium are wrung through an infinite series of changes in technique and theory. Maybe the nicest thing about this exhibit is the printmakers themselves, who will answer even the most uninformed questions about their art with enthusiasm.

Two more intimate exhibits at the Busch: Ernst Barlach, the "Transformation of Good," woodblock prints.

Barlach's woodcuts, from the permanent collections of the Fogg and the Busch-Reisinger, have been rotating around his sculpture, the "Seated Girl," all year. A new acquisition, the "Seated Girl" is indeed the focus of attention, but the latest series of prints to be arrayed around her is as intriguing as its title.

Emil Nolde, portraits.

A simple, pleasing arrangement of different aspects of Nolde's portraiture, in prints and out. The woodcuts, in particular, capture the essence of a character by their manner of execution, their style, alone.

But the best prints are yet to come: This Saturday the Busch is opening an exhibit of Josef Alber's "Formulation: Articulation" and other works.
