A couple of times we’ve shown you the distinctive work of French illustrator Jef de Wulf, and today we’re back with four more of his pieces in a slightly different vein. Rather than his usual textured backgrounds, here he works with negative white space while producing three covers for Editions de la pensée moderne’s 1950s-era Collection tropique, and one for Editions Armand Fleury’s Collection Le crépuscule. These, we think, showcase de Wulf at his best. We’ll have more later, and you can see those other covers here and here.
