Alexander Roux Chairs With Original Label
According to the label above which accompanies a pair of chairs currently for sale, these chairs were produced by Alexander Roux between 1848 and 1867 due to the 479 Broadway address mentioned.
The chairs are entirely ebonized with gold beaded trim. The label is affixed to a separate piece of fabric no longer attached to the chairs and served as the cover to the bottom of one of the chairs. I hate to see labels floating freely and not physically attached to the piece since one can buy labels and tags periodically as they come up for sale and conveniently present them along with whatever furniture they like. In this case, I think it is most likely the real deal (original label from this particular set), removed during reupholstering.
There is also a separate scrap of the original upholstery which probably inspired the color choice of the newer fabric shown above.
You don’t find Alexander Roux labels every day, so this is a rare opportunity. More at the listing.
