Every philatelic magazine has a section which lists the new stamp issues for the last months.
In Timbres magazine, it is in fact the catalogue of stamp dealer Théodore Champion, whose founder promoted the collection of unused stamps. In L'Écho de la timbrologie and Stamp Magazine, it is a small catalogue trying to follow the news with the more informations as the postal operators wants to give (to credit the artists for their work is not usual). For magazines strongly linked to a stamp catalogue, like Scott Stamp Monthly, it is a form of catalog's update that gives the reader the stamp numbers in advance.
Reading these parts is fastiduous for me, without a goal, a good topical index or an unusually long text under an issue description. See Stamp Magazine, December 2007, page 94 :
After the orthographic fault in its own country's name, the Austrian post entertains us one more time. On 29 May 2007, it issued on purpose a stamp with an error in its design. Commemorating German pilot of Italian Formula One car Michael Schumacher retirement, the 29 May stamp forgot the 1994 World Championship title. This error didn't appear on the samp issued in December 2006. Only that some already printed erroneous stamps succeeded to reach the philatelic market... and the inevitable speculation.
Austrian post's solution was to issue the erroneous stamp on 29 May 2007, and a folder with the two stamps on 26 June 2007.
I note that the 29 May stamp is not yet declared by the Austrian post to the WADP Numbering System (WNS) while the Christmas stamps already have been.
