In the world of doll and miniature collecting, an "exclusive" set is highly prized. Such items are typically produced in very small quantities for a specific event or retailer. This rarity, combined with a cohesive theme (like a village), makes the set more valuable and desirable to collectors. If the "Bobbi Jo" set was an exclusive release, it would explain why it is so difficult to find information about it online—its limited distribution means fewer records exist.
