Our theme image this week shows a dispatch rider repairing a motor cycle in France during the Great War. The August 1915 photograph is part of the collection of the British Museum which is available on Flickr Commons. There are the usual generous collection of potential themes available within this image - you don't need to get down on your back with your spanners out to find them. Whatever theme you discover, just match it with an old image from your own collection and post it on or around Saturday 19th August and add a link to the list below.
Carriages and cycles seem to be cropping up a lot at the moment - here are the next two theme images.
