Giorgio Griffa at Casey Kaplan is the Daily Pic by Blake Gopnik

This is “Obliquo giallo” ("Yellow Angle") painted in 1971 by the Italian Giorgio Griffa and now at Casey Kaplan, in Griffa’s first American show in four decades. There’s a really lovely casualness about this – the painting’s meant to be folded for storage – that has echoes of Richard Tuttle’s sculptures. What I like about Griffa’s work, however, is that it seems to start in the world of “serious”, unsmiling Greenbergian abstraction, and then let its hair down.
