Shiva and Parvati Carving

I'm interested in determining the age and value of this item. 

Item Description:
This is a finely detailed wood carving featuring Lord Shiva and Goddess Parvati, central deities in Hindu mythology. Shiva is depicted with his traditional trident (trishula), and Parvati stands beside him in a traditional pose. The composition includes several celestial attendants and ornamental elements such as floral and architectural motifs. The work is done in high relief, meaning the figures project strongly from the background, adding dimension and a sense of narrative movement.

Key Characteristics:

• Subject Matter: Lord Shiva and Goddess Parvati with attendants.
• Medium: Solid wood (likely teak or rosewood).
• Dimensions: 12” height × 7.5” width.
• Style: South Indian or possibly Nepalese folk temple art, influenced by Chola or Vijayanagara styles.
• Carving Style: Hand-chiseled relief, possibly using traditional methods.
• Mounting: Simple loop and screw on the reverse for wall hanging.
• Condition: Excellent, with minor wear consistent with age.

Estimated Age & Origin:

• Estimated Age: Likely mid-20th century (1940s–1970s).
• Region of Origin: Southern India or Nepal, based on iconographic elements and carving technique.
• The relatively unweathered condition of the wood and the absence of temple soot or insect wear suggest it was likely produced for export or private devotional use, rather than temple installation.

Market Value Estimate:

• Retail (Gallery/Online): $150 – $300 USD
• Private Sale or Auction: $100 – $180 USD
• Restoration (if needed): Not necessary at present; however, conditioning with a wood-safe oil could enhance appearance.

Recommendations:

• Conservation: Avoid exposure to direct sunlight or fluctuating humidity to prevent cracking.
• Display: Ideally mounted indoors, away from heat or water sources.
• Professional Appraisal: If you suspect this piece to be older or temple-originated, an in-person evaluation by an Indian art specialist is recommended.
