Formerly called Mind Your Manor, Amy Doherty's vintage shop in Downtown Littleton will put you in mind of your grandma's attic, stuffed to the rafters as it is with pure treasure — Scrabble tiles, typewriter keys, bits of ribbon, old-fashioned postcards, tin toys — and bona fide antiques, from pretty flowered teacups to full-sized tables and wardrobes. In spring, there's the added attraction of one-of-a-kind garden ornaments, furniture and quaint pot racks, but in winter, Doherty does up the holiday theme, making this ersatz attic a year-round joy to peruse.
