Tour de france

Yet another very simple TdF game, with a (more-or-less) 3D-board. No date provided, but must be somewhere in the sixties (after the Dutch Jan Janssen won the Tour in '68?). Distributed by a large Dutch warehouse chain. Use the spinner to determine the number of spots to move forward. Landing on 20 is (for some reason) mandatory to proceed. This game was released in the Netherlands by Hema and in Germany by Multiplay.
