79 Moons From Flickr - 51 Visible and 87 Suns From Flickr - 29 Visible by Penelope Umbrico

If you caught Lyle Rexer's panel at NYPH'09, you know he's uber-knowledgeable and enthusiastic about the subject of his new book, The Edge of Vision: The Rise of Abstraction in Photography, so tonight's talk and book signing at Aperture should be a treat!

Join Rexer at Aperture, 547 W 27th Street, 4th Floor, at 6:30 p.m. tonight.

If you're so inspired after meeting/listening to Rexer and seeing the accompanying exhibition, you should still have time later this evening to bring a little bit of the show home with you, support Aperture and their amazing programming AND save 20% — all at once! Before the stroke of midnight tonight, you can collect two works, created by Penelope Umbrico, exclusively for 20x200, in support of Aperture. Proceeds from the sale of 79 Moons From Flickr - 51 Visible benefit Aperture.

We're into the final hours of the 20x200 site-wide sale. Don't miss out!
