      The Merin Studios produced a series of twelve postcards consisting of six different designs each in two different colors (light brown and grey-green.)  The cards were made from photographs taken before the beginning of the Jamboree.  Some show Scouts posing at national landmarks.  The cards were available at the trading posts by the opening day.  The official Jamboree emblem is on the reverse of the cards which implies that the cards were published in cooperation with the B.S.A.
