During the final week of the annual “recycled” art sale at the Art Center Highland Park, the already low prices take a dive.

And this is it. The sale, which started July 26, will end August 16. Between now and then, most everything is half off.

That means ridiculous bargains on original artwork and photographs, great old posters, prints, ceramics, and scads of frames, collected all year long, mostly from donors along the North Shore. Proceeds support the art center’s classes.

Of course, a lot of good stuff went out the door before the half-off prices kicked in. This last week is for those with a serious taste for serendipity, and a love of the hunt.
