Struwwelpeter (Lustige Geschichten und drollige Bilder)

Every edition from the third (1847) onward titled "Der Struwwelpeter" is a later edition — the 1845 title wording is the discriminator, and a title page reading "Der Struwwelpeter" rules the copy out immediately. Ten stories rules it out as well; ten is the post-1847 form. Modern "Originalfassung von 1845" reprints (Thienemann/Esslinger and others) reproduce the 1845 text and title faithfully and are the commonest thing mistaken for the first — check for a modern ISBN and modern paper. One correction for accuracy: Wikipedia states the first edition contained ten stories, which is wrong; German scholarly sources (kinderundjugendmedien.de) and the Universitätsbibliothek Frankfurt agree on six stories and 15 plates for 1845.
