It was a landmark in New York's "bead alley" at 37 West 37th Street.
Walco's technique in marketing was to manufacture bead kits to encourage adults and children to make projects.
Many styles of these kits were available, mainly Native American beading belts.
In the 1930s, with the addition of the "Official Boy Scout Beadcraft Outfit", all kits came with fully illustrated, easy-to-read instructions.
These were designed for women to customize their clothes - their sweaters, blouses, dresses, scarves, stoles, and jackets.
