“This is an instant collection I found at an amazing estate sale a few weeks ago, at a brownstone uptown,” Rosenberg says. “They were selling everything in the house, but the kid had been collecting all of these No Parking signs from around New York for years. The amazing thing about this is that he took all of the parking signs for all of the days, scanned them, and then made one that said No Parking Yesterday, which is so brilliant. This was with all of this stuff in the basement. He’d made all of these greeting cards, too. He was really into Xeroxing.”
