Here are two strollers i encountered this morning, that have a very vintage look i think!
The first one is actually really vintage, dating from the seventies ; it is still used in our baby's kindergarten to go and have a walk (super sweet when 4 babies sit in there!).
The second one only looks vintage: it is very common here in Berlin for big families to go around or to pick up the kids at school.
Have a nice day!
