'Kolumbus-Eier' was published in two volumes by Union Deutsche Verlagsgesellschaft in Stuttgart, Berlin and Leipzig. The 1st edition is undated but was probably published c1899. The title pages state that these books are a collection of items from the magazine 'Der Gute Kameraden' (The Good Comrade). I learned about these books from Edwin Corrie.

A full copy of the first volume can be accessed online here.
