Partners in Preservation is stepping up their social preservation campaign this week. Each day that you cast a vote for your favorite landmark this week, tell us who you voted for in the comments of this post, and you’ll be entered to win one of five $50 gift cards from American Express. We’ll announce the winners of the cards this Friday May 18, but remember that you can cast one vote per day until May 21. Each time you do, you help divvy up the $3 million in funds to rehab and restore awesome NY landmarks, nine of which are in Brooklyn. Show some pride–vote here.
