Here are 30 exquisite postcards from Wilhelm Staehle’s Silhouette Masterpiece Theater (silhouettemasterpiecetheater.com). Each panel in the popular weekly web comic features a painstakingly detailed etching carved from a beautiful painting; the results are gorgeous and very funny. <i>Hugs and Misses</i> is a terrific Valentine’s Day gift, full of lovelorn ladies, roguish gentlemen, renegade Cupids, and indecent proposals.
