The collection provides an extensive thirty year view of the operations and products of the Minneapolis-Moline Company across the 1930s-1960s. Many images depict Minneapolis-Moline tractors, implements, and power units, both in the factory or dealer showroom and working in farm fields or other outdoor settings. There are also many images from various perspectives of machinery parts most of which appear to have been created specifically for use in sales brochures, advertising material, and catalogs. A large number of images depict the interior and exterior of Minneapolis-Moline factories, especially the Hopkins and Lake Street plants. There are aerial views of the factories, closer exterior views of specific factory buildings, interior views of the factory floor, and views of factory machinery with products in various stages of manufacture. Exterior and interior views of company dealerships and branch offices around the United States are also included. Some images document award ceremonies and rallies during World War II. Additional images show office activities, meetings and banquets in a variety of locations, and women posed as "Minnie Moline." The collection also includes individual and group portraits of Minneapolis-Moline executives, employees and dealers. This collection consists of approximately 14,180 of Jensen's negatives taken for The Minneapolis-Moline Power Implement Company. The vast majority of the negatives are of 8 x 10 size, although there are also significant numbers of 3 x 4, 4 x 5, and 5 x 7 negatives. Many of the negatives were retouched or masked. Photoprints of selected negatives were printed by the Minnesota Historical Society Photography Lab and are stored in boxes 38 through 43.
