Hello everyone,
I own this war bond, released by the city of Essen on the 19th of March 1918. Or, to be fair, the eighth part of said document. But, while looking for more details online, I have not been able to find any other war bonds from Essen, at all. I tried using Google lens and just googling the key words in general, but that did not help. There are no sale offers either when it comes to value, though that is not my main focus. But now I'm stuck. I do not own any professional literature thematising scripophily, so I have no idea what to do. So, I am asking you to help me. If anyone knows anything about this war bond or has any information in any catalogues, I would be very happy. I would also like to know if any other pieces of such a bond still exist today.

Thanks for your help in advance; have a nice day, everyone!
