Lock it up

I've walked past this window several times. I noticed there are locks attached to the front of it, but never looked at them in too much detail.

How adorable are these? There's probably around 15 of them on this one window. It just makes me think what other cute things I might have missed. It definitely helps to notice these things when carrying the camera around. Double benefits while trying to learn how to take better photos.

Are there any unexpected treasures around your neighbourhood?
