UPDATE: More information on the goal of Kaiser-Jeep’s 1966 Eastern European Caravan. This article was published on page 7 of the May 14, 1966, issue of International Commerce, a US Department of Commerce Weekly magazine. In it, the Commerce Department’s ostensible goal was as an “imaginative technique to promote U.S. Exports”, as part to the U.S. Government’s continuing effort to promote East-West Trade. It’s possible the trip was underwritten in some form (cash or government favors or both) to encourage Kaiser-Jeep to participate.
=========================
This September 1966 Four Wheeler Magazine article describes the scene when the Kaiser-Jeep sponsored Eastern European Caravan crossed into (then) Czechoslovakia, as a line of restored and refurbed jeeps awaited them. Remember, that no new parts had even available to these die-hard jeep fans since 1946, making their rebuilds even more remarkable. The Prague Jeep Club alone had more than 300 jeeps and 400 members.
