The girl writes a letter. On the postage stamp, a boy plays football with a girl, and on another, a sailor on a boat smokes a pipe. On the next, a tiger sleeps under a palm tree. Colorful images from postage stamps are beginning to come to life. The story of the letter, addressed to Jaś Kowalski, inhabited in Warsaw at 2 Bajkowa Street, is told in photographs and animated scenes.
