Each of the three stamps, as well as the sheetlet margins, contains 38 dots with corresponding numbers. By connecting the dots with pen or pencil, the contours of a bird flying off will become visible.
Even after tearing off a stamp, the drawn bird will remain clearly visible. The stamp sheetlet comprises a tricolour of pastel colours red, blue and green fading into each other. At the level of the horizontal perforations, the stripes are separated by a thin line. In the top left-hand corner of the sheetlet, an illustration of a pencil is depicted, in the top right-hand corner a fountain pen, and in the bottom left-hand corner the back of an envelope.
This bird seems to fly off the stamp, representing the journey made by the card from sender to receiver. The colour gradient from green to blue refers to the background of sky and land, from which the bird disengages to fly off on its way to freedom. The colours carry the sheetlet; that is why I have been able to keep the illustrations slight. The thin lines provide an almost etheric atmosphere.
