This commemorative pair was issued in 1961 by Deutsche Bundespost Berlin to mark the Deutscher Evangelischer Kirchentag (German Evangelical Church Congress). The stamps feature a symbolic Christian cross design accompanied by detailed architectural illustrations of church structures, reflecting the religious and cultural importance of the national Protestant gathering. Issued in two denominations (10pf green and 20pf rose-violet), the pair is valued by collectors for its historical association with post-war German religious events and classic early-1960s graphic style. Well-preserved pairs are especially desirable for thematic collections focused on religion, church architecture, or Berlin postal history.
