What a fun idea - art out of missed connections?! They can be both romantic and incredibly hilarious!
there is a whole blog of them http://missedconnectionsny.blogspot.com some of them are great there is one i love where a man wrote the ad looking for the girl that wore the other half of his furry bear costume at a costume party. the drawing is great.
