The Brooklyn Flea is a multi-platform enterprise. This spring and summer, it’s showing up all over NYC. Well, maybe that’s an exaggeration. But the Flea is procreating like a pop-up chain. Here’s an attempt to outline all their iterations.

Bishop Loughlin HS: Brooklyn Flea kicks off its third season Saturday, April 10, at its Fort Greene flagship location at Bishop Loughlin H.S. with 140+ vendors of vintage/antiques, crafts/art/design, and delicious food. The Flea will also extend its residence at Skylight One Hanson at the historic Williamsburgh Savings Bank for the rest of the 2010 outdoor season, on Sundays only starting April 11. (Both markets are open 10am to 5pm.)

Summer Stage: The Flea is also taking over the food and beverage concession at the City Parks Foundation’s Central Park SummerStage concert series, which is celebrating its 25th anniversary. Five popular Flea food vendors—AsiaDog, Blue Marble Ice Cream, Pizza Moto, Red Hook Lobster Pound, and Soler pupusas—will join renowned Brooklyn butcher shop Marlow & Daughters to provide delicious, fresh, affordable, and distinctive meals and snacks, with the goal of establishing SummerStage as a top entertainment and culinary destination. Flea food will be available at all 40+ SummerStage events from late May through early October.

Fort Greene: In 2010, the Fort Greene outdoor market will feature an expanded food section, with 25+ vendors of prepared and cooked food. All unique to the Flea, all local, and all curated for quality and professionalism, these vendors have come to embody the Brooklyn artisanal food movement. Newcomers this season include Porchetta (the East Village Italian pork sandwich shop); The Good Fork (the Red Hook restaurant serves dumplings at the Flea); Salvatore Bklyn’s new imported olive oil (the ricotta makers will dispense their new house brand from a giant metal “fusto”); The Good Batch’s Dutch-style stroopwafels; Brooklyn Soda Works (carbonated beverages featuring 50%+ juice); and new Boerum Hill Montreal-style delicatessen Mile End (hand-slicing smoked salmon and sable with Ben’s cream cheese and fresh Montreal sesame and poppy bagels).

One Hanson: One Hanson market will continue to take over the gorgeous landmark bank space every Sunday, with 100+ vendors, including several top new vintage clothing, antiques, and furniture dealers, who prefer the indoor setting. Starting April 11, the market will spill over to the building’s back parking lot, where 25 vendors, including food, will be located, along with table seating and music to create a unique indoor-outdoor setting. (The main bank space is easily accessible from the parking lot.)

Both markets will feature dozens of new vendors for the launch of the new season—from antique rugs to stitched owls to starfish jewelry to Brooklyn watches to Swedish clogs to Mr. Potato Heads to a Greenpoint used-record shop.
