Illustrated World Encyclopedia Value Guide

The Bobley Illustrated World Encyclopedia is a quintessential mid-century educational set, prized by collectors for its vibrant 1960s-era illustrations and distinctive green faux-leather bindings. Originally marketed through supermarket promotions and door-to-door sales, this 21-volume collection represents a specific era of American home learning and accessible reference publishing.

What Is Illustrated World Encyclopedia Worth?

The typical price range for Illustrated World Encyclopedia is $150 - $165 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Completeness of the set is critical; missing any of the 21 volumes significantly reduces the market value below the $150 range.
• Condition of the gold-gilt detailing, which is prone to rubbing or fading from frequent handling on the shelf.
• Structural integrity of the faux-leather bindings, specifically looking for cracking along the hinges or sun-bleaching on the spines.
• Internal cleanliness, as these were primary educational tools for children and often contain markings, foxing, or torn pages.

How to Identify Illustrated World Encyclopedia?

• Verify the presence of all 21 volumes to ensure a complete set as originally issued by Bobley Publishing Corporation.
• Check for the signature green faux-leather covers featuring ornate gold-gilt detailing on the spines and front boards.
• Confirm the publisher's imprint 'Bobley Publishing Corp' and a copyright date falling between 1960 and 1970.
• Look for the characteristic high-density of color and black-and-white illustrations paired with concise, student-friendly text.
