1. Rarity: The first edition of Tarzan of the Apes is a highly sought-after collectible, especially if it's in good condition. Original copies from this edition are scarce, as only a limited number were published initially.
2. Signature: The signature of Edgar Rice Burroughs adds significant value to the book. Genuine autographs of Burroughs are highly prized by collectors.
3. Condition: The overall condition of the book plays a crucial role in determining its value. Factors such as the quality of the binding, the presence of any damage or tears, and the overall appearance of the book affect its worth.
4. Provenance: If the book has a clear and documented history of ownership or provenance, its value can increase further. Provenance establishes the authenticity of the signature and provides insights into the book's journey over the years.
Considering these factors, a signed first edition of Tarzan of the Apes from 1914 in good condition could potentially fetch anywhere between $10,000 to $50,000 or even higher. However, it's essential to have the book evaluated by reputable experts or auction houses to obtain a precise estimate of its value.
