I've had quite a few artists express interest in being a part of the Tarot exhibit. I'm still working on the venue and specifics, but in the meantime, here's some inspiration for your creative subconscious.
Although this isn't a beautifully designed website, it does have great list of artistic tarot cards. The left-hand sidebar "Browse All Decks" has them sorted by theme and style as well as other categories.
I spent some time this morning browsing Flickr's Commons section to find interesting public domain images to use for scrap. If you haven't used The Commons before, be sure to type your search in the box that is about half-way down the page on the right. The top search box will give you everything on Flickr, most of which is copyrighted.
If you have a good source for Tarot inspiration, share it with us in the comments!
