Story
Harmony Kingdom was founded in the UK in the 1990s, renowned for its proprietary crushed marble and resin trinket boxes. Master carver Peter Calvesbert is the most celebrated of their artists, known for embedding hidden secrets—like the signature carved mouse or Swiss cheese—inside his whimsical animal sculptures. The 1996 date mark confirms this as an early-period release.

Condition & Value
Based on the provided photos, the resin body, paint application, and interior details appear intact with no obvious major damage. However, the delicate protruding elements, such as the cats' ears and tails, are highly susceptible to flea bites or subtle repairs.

Market Analysis
The secondary market for 1990s Harmony Kingdom pieces is highly saturated, with most standard-issue boxes trading as accessible collectibles rather than high-value antiques. Buyers are primarily nostalgic collectors or cat enthusiasts looking for specific models to complete their sets. While rare or limited-edition pieces can command premiums, standard production models like 'Rumble Seat' move reliably but at modest price points, heavily dependent on condition and the presence of original packaging.
Value Drivers
▲ Exact model match ('Rumble Seat') to recent sales establishes a firm baseline.
▲ Artist signature marks (acorn) and hidden interior details confirm Peter Calvesbert attribution.
▲ Early production date (1996) appeals to dedicated Harmony Kingdom collectors.
Concerns
▼ Unverified original packaging — missing the green cylindrical box and paperwork would anchor the piece to the lower end of the range.
▼ Unverified condition of delicate extremities — any confirmed chips to the ears or tails would severely discount collector interest.
Best Venue
List on a broad-reach platform like eBay or Mercari, utilizing keywords like 'Peter Calvesbert,' 'Rumble Seat,' and 'Hidden Mouse. ' If the original box and trading card are present, feature them in the primary photo and price near the $40-$45 high end with 'Best Offer' enabled. If unboxed, price competitively around $20-$25 for a faster sale.
Upside Potential
If the original green cylindrical box, trading card, and pristine, un-displayed condition are confirmed, the piece can confidently target the $40-$50 collector premium tier seen in mint-in-box asking prices.
