a Blue Pair

I found this adorable couple last weekend, a thrift store find. I picked them up and put them down more than once, but in the end, had to take them home. I can't imagine what their use was/is. I feel if they were simply figurines then they wouldn't be hollow, perhaps that's a bad assumption? Upon seeing them, I immediately thought Dickens, and Victorian England, but again, that might be a bad assumption. I also think they are someone's creation as opposed to some commercial item based on markings in the base.
