Wilhelm Staehle’s Silhouette Masterpiece Theater (silhouettemasterpiecetheater.com) is the rare Web comic that deserves to be printed. Each panel in the popular weekly strip features a painstakingly detailed etching carved from a beautiful painting; the results are gorgeous and very funny. These two postcard books feature some of Staehle’s finest work. Hugs and Misses is a terrific Valentine’s Day gift, full of lovelorn ladies, roguish gentlemen, renegade Cupids, and indecent proposals. Stars and Swipes offers a hilarious vision of classic Americana, with farcical frontiersmen, prattling presidents, and other all-American oddities.
