In fact I find the most mundane pictures of street life to be the most interesting for anything older than 30y old. But those are the pictures taken today that people today would dismiss as uninteresting when it is really what will amuse them the most in 30 years.
When I look through old family photos, the photos I want to see are the mundane ones that weren't taken surely because they were thought to be boring. Like a picture of the supermarket we patronized.
