Georg Hirth’s Munich weekly was so influential that German Art Nouveau took its name — Jugendstil, the Jugend style — and Heidelberg University Library has scanned the whole forty-four-year run, browsable page by page and downloadable as PDF. The covers change artist every issue, so a week of 1897 might open with Otto Eckmann’s whiplash lettering and the next with something entirely different. The archive also shows the ending plainly: after 1933 the same masthead carries propaganda until it folded in 1940.
