@amyk has just set up the new mundane challenge (mundane-keys) so I thought I'd give it a go.
We have a bag full of old keys that we no longer need (Apart from the star of the image which unlocks an old writing desk.)
i also used to hoard old keys then decided to throw them away a few years ago. now i only have a few, some i found in the hallway of my building, which i'm sure would open the doors of any of my neighbours. keys just fascinate me. this is a good interpretation of the challenge. mundane but not mundane. aces!
@sangwann I really don't know why we've kept them all, perhaps it's the thought that one day I might find something that they will unlock. In the meantime they make reasonable props for photography :)
Like the one standing tall.
