What's Missing - Rules of Play says:

What’s Missing? is a drawing game that contains 240 cards with line drawings, sorted by difficulty. In a round, each player takes a card, hides it behind a cardboard screen, and tries to draw another picture on transparent paper placed on top of that card, with the goal being that the drawer wants other players to guess what's on the card.
