Patent Flour Sack Appraisal

Vintage Birchmont Patent Flour Fabric Sack

This is a vintage 100-pound capacity commercial flour sack manufactured for the St. Cloud Milling Co. in St. Cloud, Minnesota. The sack is constructed from a heavy-duty, off-white cotton canvas or coarse linen fabric designed to withstand heavy weight. The central graphic features a multi-color print showcasing a tall industrial mill building beside a body of water, rendered in red, blue, and black ink. Prominent typography includes the 'BIRCHMONT' brand name in a stylized red script and 'PATENT FLOUR' in a bold block serif. Two vertical blue pinstripe accents run the length of the bag, bordering the central text. Condition-wise, the item shows authentic age-related patina including minor staining on the lower left quadrant, visible horizontal fold lines from long-term storage, and slight fraying at the top closure. It lacks the original drawstring but retains strong structural integrity. This graphic style and the manufacturer's details suggest a mid-20th-century origin, likely between 1940 and 1960. The high-quality lithographic printing on the fabric is a hallmark of industrial advertising from this era, making it a desirable example of rural Americana.
