Key Features
Company: The Sawyer Biscuit Co., which had operations in both Chicago and New York, was a prominent bakery during the early 20th century.
Product: The wallet promotes their Crispo Biscuits brand. Similar items from this era were often given as promotional "giveaways" or "gift" items to patrons or used by sales representatives.
Material: It is made of a pebbled black leather (similar to "Kurozan" or "Acadia" leather styles seen in other vintage personal effects) and features a snap closure.
Era: Given the style of the leather, gold-leaf branding, and historical context of the Sawyer Biscuit Co., this item likely dates to the early 1900s, specifically around the 1910s to 1920s.
Items of this type are collectible today as antique memorabilia related to early American advertising and food companies.
