Not to miss in NYC tonight: Lyle Rexer's talk and book signing for The Edge of Vision: The Rise of Abstraction in Photography at Aperture, 547 W 27th Street, 4th Floor, at 6:30 p.m . If you caught his panel at NYPH'09, you know he's enthusiastic about his subject and ridiculously thorough.

Since getting a sneak peek of the book back in February, we've been super excited about Aperture's summer schedule of events in celebration of the tome and corresponding exhibition. And we were happy to pair up with Aperture to launch a benefit edition with Penelope Umbrico. Umbrico created two new works exclusively for 20x200, 87 Suns From Flickr - 29 Visible (above) and 79 Moons From Flickr - 51 Visible. Proceeds from the sale of Moons directly benefit Aperture.

If you hurry home after the event, you'll still have time to collect a couple of Penelope's works at 20% off with the discount code RIDONK. The 20x200 20% more ridiculous sale ends tonight at midnight. It's an easy way to support Aperture and the excellent programming they have lined up all summer long!
