This Merklen chair (my attribution) is buried under a “Gothic Revival” description with no mention of either Hunzinger or Merklen and is posted with an expected range of $250-$350. Considering the last nice Merklen chair fetched $3,250, someone might be able to get a deal on this lot since the usual buyers of these pieces may not find it.
The chair is composed of the typical Merklen brass/wood ball and claw feet, the trademark spirals and a seat common to their designs, but this one has some extra brass: lion head finials and diminutive supports joining the seat bottom and back.
This chair will sell on December 2nd and will start at $125. More images for your review at the listing.
