A mysterious photograph

Could this be true? Urban legend or not, I find it very fascinating...

In 1983, workers who broke an old house found a box with glass negatives and wantеd to throw them.
Fortunately, among the workers was a student amateur photographer.
He printed negatives and brought photos to the gallery of photography. The author of these pictures is unknown. All of them photographed in the city of Kaunas, Lithuania in the 30th years of the 20 th century ...


PS. There is a version that the author - well-known Lithuanian photographer and ethnographer Balys Buračas.
