It's like waiting for a bus : you spend weeks waiting for one to come along and then three come along at the same time. So here are the next three image prompts for Sepia Saturday. This week it is the No, 638 we are waiting for which will take you to all places including queues, buses, raincoats, not to mention the fair city of London. Match the theme if you want, ignore it if you please. All you need to do is to get your submission linked to the list below on or around Saturday 10th September 2022. And whilst you are waiting for the next bus, you can have a look at the themes due in the next couple of weeks.
