There are 6 cards, 3 large cards and 3 small cards. Each size of card has a shape drawn on them.

Each card is placed in an envelope and two symbols are drawn on the front of the envelope to identify its size and shape printed. One symbol identifies its size, and the other identifies its print shape (but in any order).

The envelope with a large card and a diamond has the symbols “ @ , ♥ ” on it.

The envelope with a small card and a triangle has the symbols “ #, ¥ ” on it.

A third envelope with a card has the symbols “ ý, # ” on it.
