Generations of Perambulations

Today at the local vintage market, a very good source of candid photography, I caught these three "girls" with their prams and noticed the difference in age between them all. When i looked at the shot on my computer, I realised that it's not the sort of photo you get a chance to take every day, so I have decided it is unusual enough to be my Blip for today, and in monochrome, of course!
