DDR Chickenstamps

Today got a serie from the DDR (23 january 1979.) The first 5 stamps you see more than the last one. In the DDR the stamps with the highes value were issued in the lowest quantities. Normal, because you need less of them. The first one , Chabo( Japan Bantam), 15.000.000 stamps, the last one Italianer with streeps, 2.100.000 , and had to get. I also did not have that stamp till now.

Most of the issues in the DDR are CTO stamps, think some of these are not.
