Royal Bonn Portrait Vase Value Guide

Produced by Franz Anton Mehlem between 1890 and 1910, these Royal Bonn portrait vases represent the pinnacle of late Victorian German porcelain. They are highly collectible for their intricate hand-painted central panels and the factory's signature 'tapestry' style finish that signaled high social status.

What affects the value of Royal Bonn Portrait Vase?

• The presence of a known artist's signature on the hand-painted portrait panel significantly increases the $750-$825 valuation.
• Condition of the gilt and bronze elements, as rubbing or loss of gold leaf can decrease the item's market price.
• The complexity of the portrait subject and the preservation of the original porcelain lid.
• Rarity of the specific vase shape and the vibrancy of the surrounding floral or tapestry motifs.

How to Identify Royal Bonn Portrait Vase?

• Look for the 'Royal Bonn' trade name and the Franz Anton Mehlem (FAM) monogram stamped on the base.
• Examine the central portrait for a hand-painted artist signature, which distinguishes premium pieces from mass-produced transfers.
• Verify the presence of authentic late 19th-century gilt bronze or ormolu mounts and a matching porcelain lid.
• Check for the characteristic 'tapestry' texture or heavy gilding typical of the 1890-1910 production era.
