Lesja Ukrainka (fourth from left) among relatives and friends.
Zelenyj Gaj (Green Forest farm), summer 1904.
If I properly define among the guests Olga Kosach-Kryvynjuk, Michael Kryvynjuka and Anton Szymanowski, this photo made in Zelenyj Gaj at summer 1904. Lesja Ukrainka stayed there from 4 (17) June to 12 (25) September; Olga Kosach left earlier – 12 (25) August; A.Shymanovsky left even earlier – sometime in early July (old style). For these reasons, one can narrow the dating of photo to the interval: beginning of June – beginning of July 1904 (old style).
In the "Chronology" O.Kosach-Kryvynjuk indicated:
In the summer of 1904 in Zelenyj Gaj was Peter Kartashevsky and repeatedly photographed all groups.
Apparently, this photo was taken by P.Kartashevsky.
