Decorate your correspondence, notebook or any other non-digital goods with The Portland Stamp Company's Analog Stamps, the upside-down stamp a little nod to the perfect imperfection of hand-created goods. Printed on adhesive gummed paper in Dayglo blue ink, edges are pinhole perforated by hand with The Portland Stamp Company's antique perforator. To adhere stamps, moisten with water although we think applying with a glue stick yields the best results.
