Rob Bontenbal, Homas, Netherlands, 1970's.
Original edition of the game better known as Um Reifenbreite or Demarrage. I prefer this original 70s artwork. The Game Cabinet takes a look at the small differences between the two editions.
Jurgen Muns has programmed a free computer version of this game which can be downloaded here: http://homastour.tripod.com/
Ruben in t' Groen has developped a new set of rules for Homas Tour. Although he calls them "Homas Tour Pro", they are different enough to be considered a different game.
