First Computer generated stamp motif.

The first series of five stamps with computer-generated motives world wide was made in the summer of 1970. The particular challenge lies in the very small size of only 22 × 22 mm. On one of the stamps one of the circle elements of the Bremen work is to be found. The work of the Kunsthalle Bremen is particularly attractive due to its strong moire effect, as it is known from Op Art.
