I've found yet another great online art marketplace. The Beholder, in founder Suzanne Shade's words, is "devoted to showing and promoting emerging and mid-career contemporary artists." That means slightly more expensive, wonderfully polished artwork of varied styles and media. Beholder works as a representative (and takes commission on) some of the artists; in other cases, you buy directly from the artist. And because the price point is slightly higher than, say, Etsy, Beholder builds in a guaranteed seven-day trial period (like any high-end gallery would do); if your piece arrives and it isn't what you expected, or it doesn't work in your space—no worries. But something tells me you wouldn't be returning any of these.
