Original etching by Tavik Frantisek Simon, signed with the artist's monogram in the plate. Printed in red-brown on cream wove paper by K.K. Hof -und Staatsdruckerei, Vienna. Published by Verlag der Gesellschaft fur vervielfaltigende Kunst, Vienna. This etching was first issued in 1909 by the same publisher in a signed edition of 125 (with 10 artist's proofs) on Japan paper; this is the 1911 printing for Die Graphischen Kunste on wove paper. There are printed credits below to artist, title, printer and publisher. The title is given as Die Eroberung der Luft (The Conquest of the Air). There are just a few tiny spots in the outer margins, well away from the image.
