This Moshe Rynecki Passover Seder scene appeared in Nasz Przeglad Ilustrowany 1938, number 16, page 5. The whereabouts of this painting, and whether or not it survived the Second World War, are unknown.
I also know that my great-grandfather painted a series of pictures based on the Haggadah, but that the images were never printed and that the work was lost in the war.
Good Pesach to you and yours.
