  The present work revisits the classical Wulff problem restricted to
crystalline integrands, a class of surface energies that gives rise to finitely
faceted crystals. The general proof of the Wulff theorem was given by J.E.
Taylor (1978) by methods of Geometric Measure Theory. This work follows a
simpler and direct way through Minkowski Theory by taking advantage of the
convex properties of the considered Wulff shapes.
