The idea of the Passerelle des Arts pedestrian bridge is that you and your lover place a lock on the bridge and throw the key in the Seine River. Here's a link to some photos of the bridge: http://www.tumblr.com/tagged/lovers%20bridge.
Well!!!! My amazing husband never misses an opportunity to let me know that he listens and I had a birthday coming up!!! So he made this piece for me. I LOVE nothing more than homemade presents that let you know the person gets you!! Since we couldn't physically go there now, he brought the sentiment of the bridge to me!! I've shared photos below. :) <3
