Foto de stock - ***JUNE 1st, 1973, FILE PHOTO*** The twenty-two-member collective of Moravian Oil Mines technicians competing for the Socialist Labour Brigade (BSP) title, led by Zdenek Stokman, made a socialist commitment earlier this year to exceed the plan for the volume of geological exploration work, which amounts to 106 million CZK, and to save one million CZK on materials. They were able to make this commitment on the basis of the successful work results from last year, when they exceeded the volume of work by more than four million and saved almost two million crowns on materials.
