No sender?

recipient:
Jurko KUTSCHERUK
„Schiwotowka, Oratowo“

There doesn’t seem to be a sender`s name or address.
But maybe there are notes in Cyrillic somewhere that would help identify the sender? - @mally

I already had two cards sent to the same recipient, written by Maria and Natalija KUTSCHERUK - see here.
(To me the handwritings in the text fields of these 3 cards look kind of different, but I’m not sure..)

postal stamp: I entered „unclear“ in „place“
Could it be „Stuttgart“? like in the card by Natalija?
