I recently decided to reupholster this platform rocker which my father bought at auction 30+ years ago. Upon taking off the arm coverings I discovered an old torn and worn label. I’m wondering if this is from the Zangerle company (even though Zangerle is from Chicago and this says Portland, ME) and the approximate age of the chair.
Your chair in in the Eastlake style which was part of the late Victorian period !! Could have been made any time between about 1880 and early 1920`s !! Charles Eastlake was an English designer and never made furniture himself !! He wrote a design book Called “Hints on Household Taste” which tried to eliminate the overly carved ornate look of the Victorian period !! Many mfrs made this style furniture !!
I am not sure but the label on yours may be a shipping label since the Mfrs name is at the bottom !! Zangerle only made the wooden frame,, it would have been upholstered after arriving at its destination I think !! Perhaps that is why it was under the upholstery !! The name at the top may have been the company that did the upholstery or the person who purchased it !! It was not unusual for someone to purchase a piece in Grand Rapids or Chicago and use it in their summer home in Maine !! It was a different lifestyle back then,, if you had money !!
