i print these notecards individually on my studio printer, see making prints. notecards are made with the same archival quality paper and ink as a full size print. if handled with care (and cotton gloves) they can be matted and framed having the same longevity as the larger print.
each card is sealed in a cellophane sleeve for protection with a recycled envelope for mailing.
rectangular images are printed on a full size, 8.5" x 11" paper, when folded finishes at 8.5" x 5".
panorama cards finish at 4" x 9", which is a standard #10 - business envelope size.
i have a display rack of these notecards at my studio/gallery.
