Okay, so it's not my photo, but a scan of a found image. In the early 20th Century postcards were a craze, the 'Facebook' of their day. At one point time there were six posts per day, making them an easy and fast way to communicate. At seaside resorts, local photographers could quickly prepare a photo of your happy family on holiday to send to friends and loved ones, as in this example.
So what's going on here? From the layers of clothing it looks like they've gone on holiday in January. Dad looks like he's spoiling for a fight, Mam's not far behind, and I believe the child is crying! Yet this is the image they paid to have printed on a card.
