I was enamored with all of the objects in Three Potato Four's booth at the the Brooklyn Flea Market. Do those giant letters and numbers call out to you too? I saw them from across the room and was magnetized to that big red '5'.
They have a fantastic online shop with lots of vintage finds and new creations, including this Manhattan poster print by Jim Datz that I have seen featured all over the web.
Three Potato Four also has a blog.
