Ah, the Magnet Lady. First, Mona sets up shop in a corner of a wedding reception, a bar mitzvah, a quinceañera, or whatever special event you may host. Then, she asks passersby to pose for a photo or three, with whomever they like. Now comes the good part. Before you say your goodbyes, just drop by Mona's booth and pick up the black-and-white photograph she took of you and yours. The photo isn't just a photo, but now, cleverly, a magnet for guests to stick on their refrigerators, filing cabinet or wherever as keepsakes. The woman oozes enthusiasm for her self-created gig, which has been a big hit at the three or four events where we've seen her work. And don't worry — she doesn't seem to do too many close-ups.
