There are brothers — Marky, Ricky, Danny, Terry, Mikey, Davey, Timmy, Tommy, Joey, Robby, Johnny, and Brian. And then there are brothers of the unrelated variety. We proudly introduce The Post Family: Chad, Rod, Alex, Scott, David, and Sam Post, six designers, and partners in crime. (And no, they’re not really related.) Last April, the gang decided they needed an outlet outside of their full-time gigs to make art for art’s sake. So they pooled their resources; rented a studio; ripped off an 800-pound letterpress from an 82-year-old woman (legally); and now create quirky, rad designs in-house. From posters and prints to T-shirts and stationery, the boys silk-screen their wares in a darkroom they built themselves. If the Make Your Own T-Shirt Kit doesn’t get you jazzed, maybe one of Rod’s Polaroid prints will. Clearly, talent runs in the family. Available online at thepostfamily.com. Open house, tomorrow, 5-9 p.m., at The Post Family Studio, 1821 West Hubbard Avenue, suite 308. R.S.V.P. online at openhouse.thepostfamily.com.
