Zionist Socialists of Myr, Russia 1906
"A Group of Zionist Socialists of Myr, Russia taken a quarter of a century ago [1906]. Most of them have since arrived in this country [U.S.A.]"
Note: the young man at the far left of the second row is of particular interest. Leon Mirsky was born in 1890, arrived in the U.S. in 1908 at age 18. In 1906 he would have been 16 years of age. I have no other evidence but the young man bears a resemblance to the photos of Leon in this gallery, and the age is about right.
