Here we have two cabinet cards of Uncle Karl Trunk and his family. The first is from the 1890s, which we can tell by the deckled edges of the card. Also, there are three girls in the first photo, while the second shows four girls and a boy.
I find the setting of this second photo really unusual. It looks like they are sitting in an alleyway between two houses. The brickwork is wavy, as though the ground settled after the bricks were lain. There is no photographer information on the photo. However, I’m going to date this in the 1900s because of the ages of the children. The youngest girl in photo #1 looks to be about 8 in photo #2.
