Railways, photography, the motor car, film and radio: some of the key inventions of the last two hundred years that have done so much to shape the world we live in now. This week, on Sepia Saturday, we celebrate two of these - photography and radio. Our theme image shows a photograph from eighty years ago of a man using a radio transmitter. All you need to do is to imagine that he is inviting you to share your hold photographs on Sepia Saturday by posting a post on or around Saturday 31 May 2025 and add a link to the list below. After which you can look forward rather than looking back - and see what is to come on Sepia Saturday over the next few weeks.
