Vectorize 29 Board Game Illustrations

I have twenty-nine memory-game illustrations currently supplied only as JPG/PNG files. The art itself is final—I do not need new concepts, colour tweaks, or layout changes. What I need is clean vector conversion so the files can withstand offset printing without loss of clarity...
