I can't believe I didn't think of this idea earlier: vintage postcards! In Domino this month they suggest using old holiday-themed postcards as holiday decor orfor your own Christmas correspondence. A quick check of their source (Ebay, naturally) yielded a metric ton of Atlanta-themed cards.
Think about it, the uses are endless: Save the dates, invitations or RSVP reply cards, table numbers, strung on a line with clothespins for general decor! I can't wait to strike a deal with one of the sellers to send over a whole stack. And look at the Emory one they are listing from the 1930s! Golden!
