This button is advertising the Chicago-based year round turkey company, Peter Fox Sons Co. The company was created in 1897 and was run by nine Fox brothers when their "DeLuxe" turkeys went on sale. They were the first company to teach turkey-growers how to "dress" their own birds, saving the company time and benefiting the growers with more money. They were also the first company to pack and sell turkeys under a private brand; this "DeLuxe" brand is what this button is advertising for.
