Instead of a traditional guest book, Jen and Chris asked their guests to write their well wishes on the back of Polaroid photos and place them in a vintage suitcase. Making the most of their unique space, the pair used the vibrant “Welcome to Greenpoint” postcard mural as the backdrop for the photos. “It tied in perfectly with my vintage postcard escort cards that I picked out personally for each guest. Each card represented their home state,” says Jen.
