r/PopArtNouveau is pretty awesome though, so take the risk and dive straight in.
In this subreddit, users post both original content (like the picture above) and content that they have found other places. The subject matter is pop culture reference drew in an Art Nouveau-esque style (usually channeling Mucha).
If nothing else, it can give you Pinterest boards a perk with some new, beautiful content.
