Old DDC Swag
These two sets of cards were produced by DDC Inc. 'way back in the day (1978 was DDC III!), and given away in swag backs to all attendees.
Note: If you're looking for the DDC-branded merch that now appears at the con, check out our Merchandise page. We will have a table in the Dealers' room for purchases. We're not set up to distribute this good stuff between conventions, but whatever we have left from past years will be available at the DunDraCon table in the Dealers' Room.
