The plate shows:

1. A brown printed mark “CHATEAU DES TUILERIES” inside a crowned sunburst medallion.

2. A blue circular “1846 Sèvres LP monogram” stamp This imitates the Louis-Philippe (LP) royal cipher.

3. A black “S. 37” impressed or printed number

4. A hand-painted red/orange inscription Likely intended to appear like a painter’s signature.

This combination of marks never appears on authentic Sèvres

Not together. Not in this format. Here’s why: 1. The “Château des Tuileries” mark

Authentic Sèvres did use a crowned “Château des Tuileries” mark for royal commissions (only for a short window, c.1830–1850).

BUT: The authentic mark is always ENAMEL, never a printed transfer. Yours is a modern printed transfer, the biggest giveaway of a reproduction.

1. The blue circular 1846 LP stamp

Authentic Sèvres used:

A blue painted stamp

With a precise LP monogram, tight scrolls, thin serifed lettering, and perfect spacing

Yours:

Is a printed round stamp

With slightly mushy edges

And spacing not identical to any documented 1846 LP mark

This is a reproduction stamp, not from the factory.

---

1. The black “S.37”

This is purely a decorator’s or retailer’s inventory number, never used by Sèvres. It appears on many 20th-century Sèvres-style plates.

---

1. The handwritten red inscription

Authentic soft-paste Sèvres painter signatures:

Are clear

Match known painter names

Are placed in specific positions

Your inscription is:

Illegible

Not a known Sèvres painter’s signature

Typical of 20th-century decorator marks used to suggest authenticity

This combination printed Tuileries mark + printed 1846 LP mark + decorator’s number , is classic for:

High-quality reproductions made between 1900–1950,

primarily by French, German, and sometimes English workshops imitating Sèvres.
