This is a beautiful, authentic Victorian-era bone china teacup and saucer set by Royal Crown Derby. It features the highly collectible "Peacock Blue" transferware pattern (Pattern #3775), depicting intricate peacocks perched among dense floral branches and foliage.

Both pieces feature the early Osmaston Road factory backstamp (Crown over interlinked 'D' monogram) without any country-of-origin text, definitively dating this set between 1877 and 1890.
8n very good antique condition with NO chips, NO cracks, NO hairlines, and NO restoration. Both pieces retain a lovely glaze and ring clearly when tapped.
* **Gilding:** As is common with 19th-century tableware, the gold gilding on the rims and handle shows noticeable rubbing and is missing in parts due to age and historic use. Please study the close-up photos carefully to assess the gilt wear.

This is a wonderful, honest piece of late-Victorian English porcelain—perfect for a replacement seeker, a daily-use antique tea service, or a charming addition to a blue and white china display.
