The Legionářské
Almost ironic is the fact that the Legionářské stamps, intended for semi-postal use in support of the orphaned children of Legionnaires killed in the Great War, became philatelic orphans themselves. Valid for a single week in 1919 and for domestic use only (some do appear on refused foreign mail), the remainders were given as a grant-in-aid to the agency responsible for raising funds for those orphans. A series of mishandled and unofficial releases, overprints, perforations and other shenanigans gave these stamps an undeserved poor reputation in the philatelic world. Recently their standing has improved.
Actually, the typographic Legionářské picturing the two-tailed Bohemian Lion, were the lower values of a combined issue and served to commemorate the first anniversary of the republic; they might better be called the First Jubilee Issue. The higher value stamps, picturing a mother and child and bearing the legend "For the orphans" were the semi-postal part of the issue and are the true Legionářské. Some philatelic writers wish to change the name from their Legionářské misnomer to The Jubilee and Charity Issue of 1919. While this newer name does not sing, it is at least more representative of the intent of the combined issue.
All of the Legionářské were supposed to have been released in the same quantities -- 5,000,000 -- on the same day, October 28, 1919 and withdrawn from service a week later on November 3, 1919. There is evidence that the stamps were available to the public a day earlier, October 27, 1919 and they appear postmarked a day or so after their withdrawal.
