Aisengard and Mrs. Nadia

Probably a nephew of Tuba Aisengard.
You can read a note Aisengard y Sra. Nadia (Aisengard and Mrs. Nadia)
In the back of the picture there's the following text in russian:

For the good memory to dear Nephew and Niece, to (she-)cousin and to brother (may be the "he-cousin" an not the brother is meant j.a.) Aron and Klara Erlikh
From the Aunt and (she­)cousins and (he-)cousin Eizengarden (or Eizengard?)
Odessa November 2, 1906

We can deduce that the sender was the aunt of Aron Erlichman (married to Clara Likerman) so the sister in law of Tuba Aisengard. Seems to be the wedding of her son, the cousin of Aron.
