[1] Even before the formalization of the Esperantist movement in the GDR, there had already appeared a ten-page 1960 Esperanto booklet published by the German Peace Council.

Edited by Ludwig Schödl (Neuruppin) and Karl Maier (Berlin), it had a circulation of 6,000 copies.

In addition, the annual special issue from the GDR brought more content and had better design.

These editions of PACO contained material about international political problems and multiple cultural articles, as well as notes on interlinguistics, esperantology and studies of the advance of the Esperantist movement in East Germany and abroad.

To be of a similar standard to widely circulated publications, it had the collaboration of professional graphic artists from the Dresden editorial office of Zeit im Bild.
