Passover Seder at 4222 Wabash, 1947 "Trilly" (?). See notes
The word "Trilly" was written on the back.
L to R: Kolman Baellow, ? Unknown, Abe Cohn, Hike Cohn Schulman, Marietta Ritz Cohn, Morris Tulchinsky, Eva Cohn Tulchinsky, Bertie Cohn Levin
And because I'm such a geek here is a link to the framed photo in the background:

It's of Yisroel & Leah Komar holding Maya w Mikhail Kushnirevich & Hinya Anna Komar. Yisroel Komar was Fayga Devorah Komar's brother. Fayga Devorah was married to Kolman Baellow. So, it was the family of the brother in law of Zayda Kolman, who is pictured on the left.
I think the frame on the right holds a JNF tree certificate that was planted in memory of Libby Cohn who died 8 years before this picture was taken in 1939.
Wonder if the unknown person is a cousin/relative from Minnesota or just a friend.
