Above are a pair of covers by French illustrator Jacques Leclerq, aka Jihel, who by coincidence went in a similar direction on both, though it looks to us like the top book, 1957's 3 filles en folie, features his trio of filles in a somewhat paradisiacal setting, while the the bottom one, 1953's Le temps des filles, features them in a place that looks a lot like hell. We bet the trio in hell are more fun. See more from Jihel by clicking his keywords just below. 

Above is another fun cover from French illustrator Jacques Leclerc, who also signed his art as Jihel, and here works his magic on Roland Patrick's The Lost Nights. We've featured this artist several times. See more here, here, and here.
