Official depictions of the eagle can be found not only in the federal coat of arms but also on the federal institutions flag, the standard of the President of Germany and official seals. These are designs by various artists of the Weimar period and differ primarily in the shape and position of the wings. A large and rather plump version of the eagle decorates the chamber of the Bundestag, the German parliament; it is sometimes called Fette Henne ("Fat Hen"), with a similar representation found on the German Euro coin. In addition to the official depictions, artistic renderings of the federal eagle are permitted and have found their way onto coins, stamps and the letterhead of federal authorities. In 1997 the Federal Press Office implemented a slightly simplified version of the original von Weech seal design which has since been used as a corporate design of the Federal government especially for publications and media appearances. It has no official status though as it is not mentioned in any ordinance or shown in the binding patterns of 1952 still in effect.
