Thank you, Louise, for your email today about Artsy.
Louise found my blog via my post about Alexander Calder and asked that I link to Artsy's Alexander Calder entry - which I gladly did. You'll see it on the right in the sidebar.
The mission of Artsy is to make all the world's art available to anyone with an internet connection. Please find time to check out their site - and bookmark it for future visits. There's a world of treasures there.
