The Danish version of Bondespelet, was made in the 80 and published by Alga.
The cover was different from the Swedish and Finish version from the same period. On the Danish image there is a photo of a large farm with an Ursus C-385 DeLuxe tractor (yes, I googled it!).
The exact year is unknown, however upon the oldest dated check signed by previous players, there is one check signed 6th of January 1982, so the game must be from before 1982.
