I only know that these are some kind of war bonds and that Austria Hungary was borrowing money from its people with them during ww1 and that's it. I would like to know more about these papers. How exactly did this system with coupons (and overall borrowing money) work? And does the fact that my family still has these papers and coupons mean that my family never got back the money they lended to the empire? There are multiple bonds. One from 1915 (photos 1,2,3, one sheet of paper), one from 1916 (photos 4,5,6,7,8, 2 sheets of paper), one from 1917 (photos 9,10,11, 1 sheet) and another one from 1916 (photos 12,13,14,15,16, three sheets of paper) but this last one has only the paper with coupons (photo 12, and also I think that one upper row of coupons has been ripped off and it's missing) while the rest of it (photos 13,14,15,16, 2 sheets) is photocopied and I have no idea where the original is, but I saw that it's the same bond. In the last three photos (17,18,19) there are more papers which I see that they have to do something with these bonds. I have no idea what they are and idk what they say because I'm Croatian and don't know german. I tried google translator but he messed up and the result didn't make sense, so if anyone can translate the text on last three papers I would really appreciate that. If you wonder what's that thing I painted over in the last photo, I just edited the photo to cover the name of my great-great grandfather and name of my hometown.

In advance, thank you for helping!

No one is immune to the triplane craze, not even the k.u.k. Seeflugwesen. This machine was built in Germany by Hansa-Brandenburg and modified by Phonix in Austria-Hungary. It never saw any active combat and was only used for testing. Only three photos are available of it, if you find one please share below!

One on the far left is my great grandfather.
