Specific Steve being an artist fic

[janne-d.livejournal.com]

I'm looking for a fic that has Steve exhibiting paintings that he has done that symbolically represent the rest of the Avengers - they aren't portraits, but images that fit each of the others. I remember that he has done so secretly from them and under a pseudonym and that Natasha finds out by accident because she goes to the gallery - she isn't happy about it at first, but then (I think) she sees Steve there and realises that he painted them and I think she might end up buying one of them?
