The DNK stamp catalogue serves as a comprehensive reference for all German stamps, encompassing old Germany, Danzig, Memel, Saar, the colonies, and the occupied territories of the two world wars, along with local issues. In addition to the primary stamp releases, it also provides coverage and assessment of the most significant variations in color, watermark, and perforation. The catalogue includes illustrations of the diverse stamps from Berlin, the GDR, and the Federal Republic of Germany, facilitating quick identification and classification of the issues. For advanced collectors, the catalogue offers a wealth of information in various appendices, encompassing se-tenants, stamp booklets (Bavaria, German Reich, Gdansk, Saarland, etc.), and the joint issues of the Federal Republic and Berlin.
