I thought I would give you guys some close ups of the paintings so you can see what's going on in the background. This is where all my research comes through and gives some context to the paintings.
In the bottom left I have included Marie's sister Bronia. She's important because the two had a pact that the one would help the other through college because the family was too poor to send both to school. Marie worked and earned enough money to put her sister through university and after she graduated Bronia helped Marie do the same.
