Instadibs. I sooo wish I still had that poster, which went missing during one of my moves.)
But one day I stumbled across an arts fair in a park near my apartment and discovered I could buy ORIGINAL ART for the same price (or even less) than a copy of the Picasso Don Quixote print (you know the one) or the reproduction of Ansel Adams "Moonrise over Hernandez, New Mexico (you also know that one, and did you know the bidding started at more than half a million when a print was auctioned by Sotheby's in 2006).
Then eBay came along and suddenly you could buy art from all over the world. It wasn't necessarily cheap--I paid $500 for a painting by a Vermont artist who signed her paintings VERTE--but the works were original and I wasn't going to see them in every corporate waiting room and low-end motel in the city.
Then I discovered Red Bubble. And Etsy. And well, let's just say that I now choose my living quarters by how much available wall space there is.
Art is a great gift to give people but it's so very, very personal that unless you know someone REALLY well, the best thing to do is buy a greeting card that's an art piece you like and then enclose a gift card for a site your friend might enjoy browsing.
On Redbubble, posters begin in the $12 range and go up, depending on size. You can get something like one of Tanyashatseva's dreamy, spacetime inspired glitter-infused acrylic paintings called "Nahdezhda Nebula") as everything from a sticker to a phone case to a t-shirt to a greeting card if you don't have room for a poster.) You can even get the image on leggings!
Other sites with original art for sale are:
Root Division (a gallery in San Francisco) also has terrific art in the $200-$500 range, but it's only available for local pickup. That's a shame because there's a piece by Eva Enriquez that calls to me.
Life needs to be beautiful. Do your part. (And remember, no matter how awesome Georgia O'Keefe is, friends don't let friends hang posters of her bones and flowers.
