There's that familiar anecdote: a child gets a nice, big, expensive toy for his birthday. The parents have spent hours putting it together,. For all of their sweat, pain, and suffering they find that the child is most fascinated with the big cardboard box the toy came in.
Cardboard, by Doug TenNapel, is a clever variation on that premise. Mike, an out-of-work carpenter, has nothing for his son Cam's birthday. A strange old man approaches him with an offer. For just a handful of change, Mike can get his son an amazing gift. It may seem like an ordinary cardboard box, but whatever Cam makes out of the corrugated paper pulp comes to life.
