For those who enjoy American Art and happen to be on Facebook, I'd highly recommend checking out the page for Questroyal Fine Art, an art gallery in New York City. I knew little of this gallery before discovering their website after reading about one of their Hudson River School exhibitions. The Publications portion of their site actually allows you to access lo-res PDFs of their exhibition catalogues. Very cool.
Anyway, their posts on FB are both interesting and frequent enough (usually just once a day) without inundating one's news feed. It's always nice to scroll through my FB friend's list and randomly see a beautiful Thomas Moran view of Venice or a Fitz Henry Lane port scene over the sunrise.
