Most walking pictures date from the early 1920s onwards, with just two in my archive from before WW1. This looks to be a third. The card is very faded and frustratingly has no location or indication of which firm took it. Not does it carry the usual reference number, just a regular postcard printed back. But it clearly is a commercial walking picture from the composition and the way the woman is looking with curiosity at the camera, he waving his stick in the general direction seems to be trying to ignore it. The dating comes from her fashions, and also his collar.
Being so early, it is before negative numbering had come into use on walking pictures, and the couple were probably just informed where they could see the print on display later in the day (maybe in the kiosk in the background), and did indeed go and buy it.
It’s not a brilliant image but that’s mostly because it probably wasn’t processed as well as it could be, so it is now a very pale sepia colour which I’ve had to work on in Photoshop to increase the contrast.
The view has a south coast feel to it, but the depth of field is quite shallow so everything behind the couple is very out of focus. If the area looks familiar to anyone do get in touch! There is a hi-resolution version in the Go Home On A Postcard book.
