This card shows the Hebrew alphabet. Remember that you have to read it from right to left. To each letter, the designer assigned one town in Israel beginning with that letter, for example Eilat in the south or Haifa in the north. The drawings show typical scenery of those places.
The stamp is from a series commemorating the International Year of Astronomy 2009, 400 years after the first astronomical observations with a telescope by Galileo Galilei. This particular stamp shows modern gravitational lensing.
